Application

The BDC-44 is a very powerful mobile dust extractor. This high performance machine is exclusively designed and built to be used in combination with Blastrac machines. It is equipped with 4 pieces of specially designed high quality M-class cartridge filters. The dust extractor is provided with an air pulse cleaning system which increases the life of the filter cartridges. This system works by use of pressurized air, built up by a belt driven compressor. The conditioned air then passes a control valve which regulates the system pressure, and then builds up pressure in the pulse tank. The pressurized air is used to generate a pulse of air which cleans the filters from the inside. With every pulse of the pulse system, dust and particles are released from the filter surface. Contact Blastrac B.V. for the correct execution and combinations.

6. Maintenance Pay attention to Chapter 3 "Safety" during maintenance and repair works. Failures due to inadequate or incorrect maintenance may generate very high repair costs and long standstill periods of the dust collector. Regular maintenance therefore is imperative. Operational safety and service life of the dust collector depend, among other things, on proper maintenance. The following table shows recommendations about time, inspection and maintenance for the normal use of the dust collector.

Operating hours/

time period Inspection points, maintenance instructions

12 h after repairing Check all accessible screw connections for tight seat.

Daily and prior to starting work

Check that all safety devices working adequate. Check the electric connections for sediments of dirt or foreign bodies. Check the electric motors for dirt and other contaminants. Check all safety devices working adequate. Check the function of the residual current operated device. Check the hose connections for tightness and fixed seat. Check all hoses on the machine for damages or leakage. Make sure that the dust bin is emptied Make sure there is no water in the air pressure tank.

Every 3 months Clean the upper section of the filter unit. Clean or replace the air filter of the compressor. Check the tension of the V-belt

Annually Full overhaul and cleaning of the complete machine.

The time indications are based on uninterrupted operation. When the indicated number of working hours is not achieved during the corresponding period, the period can be extended. However a full overhaul and a technical inspection must be carried out at least once a year, consisting of inspection of filters for damage, air tightness of the machine and proper function of the control mechanism. This technical inspection shall be carried out by the manufacturer or an instructed person. Due to different working conditions it cant be foreseen how frequently inspections for wear checks, inspection, maintenance and repair works ought to be carried out. Prepare a suitable inspection schedule considering your own working conditions and experience. Pay attention to unusual noises or strong vibrations. Check for the cause of every big change. Call a technician if you have doubts about the cause or when a repair without a technician seems not possible without damages. Only use genuine Blastrac spare parts. Our specialists will be happy to assist you with more advice.

17

Prior to any repair works on the dust collector and its drives, secure the dust collector

against unintentional switching on. Put the dust collector to its safety off position. Also

make sure there is no air pressure on the pulse system.

Follow additional operating and maintenance of OEM if included

during your service and maintenance work.

Further is advised:

Store the cleaned and dry machine in a dry and humid free room. Protect the electrical motors from moisture, heat, dust and shocks. All repair work must to be done by qualified Blastrac personnel, this to guarantee a safe and reliable machine. Any guarantee on the machine is expired when:

Non original Blastrac parts have been used Repair work is not done by qualified Blastrac personnel Changes, add ons or conversions are undertaken without written permission of Blastrac BV

Screws, bolts etc. that have been removed must be replaced with those of the same quality, strength, material and design. Do not weld, flame cut or perform grinding works on or near the dust collector. Danger of fire or explosion exists! Provide adequate ventilation when working in a confided space. Secure the maintenance area if necessary.

6.1 When to change the filters?

If the dust collector loses suction power first try the following before continuing:

1. Check if the silencer is fully opened. 2. Ensure that the compressor is fully pressurized and then turn it off. Remove all moisture from the

compressed air tank by using the drain valve. Turn on the compressor again until it is fully pressurized again, now use the air gun to completely empty the pulse tank.

3. Only turn on the compressor, and keep the fan unit turned off. Let the machine pulse for about a half an hour. This action will clean the filters from the inside.

When the machine still does not perform adequately, the filters probably need to be exchanged. If the silencer blows out dust, stop the machine immediately!

This means probably that a filter is damaged or not fitted properly inside the filter chamber. Check the filters and replace if necessary. When a filter was damaged, has leaked or was mounted incorrect, it has to be replaced. The compartment above the filters, the connecting air hoses and the silencer also have to be cleaned thoroughly. Continuing work with a broken/leaking filter can cause serious

damage to the machine and is a health hazard!

Never expose the filter cartridges to moisture!

6.2 Changing the filters

Read chapter 3.6 Maintenance safety before changing the filters. Operators should observe any safety regulations appropriate to the materials being handled. Warning! Always wear Personal Protective Equipment, the dust can be hazardous to the health!

Make sure you have enough sturdy plastic bags or use big bags for the disposal of the old filters. Observe the national regulations in force both during exchange and disposal of the old filters.

Remove the filter house door.

Loosen the nut+washer (2).

Remove the locking bar (1).

The filter bracket will now be tilted downwards so the filters can be taken out easily.

Slide out the filter (3) and put it in a sturdy plastic

bag.

Close the bags properly.

When mounting new filter cartridges pay attention that their gaskets at the upper side lies firm at the sheet steel of the filter chamber. A tilt of the filter cartridge results in leakage and contaminants will be sucked in the clean part and consequently will blow them backwards in the outer air.

When a filter was damaged, has leaked or was mounted incorrect, it has to be replaced. The compartment above the filters, the connecting air hoses and the silencer also have to be cleaned thoroughly.

If the silencer blows out dust, stop the machine immediately!

This means probably that a filter is damaged or not fitted properly inside the filter chamber. Check the filters and replace if necessary. Continuing work with a broken/leaking filter can cause serious damage to the machine and is a

health hazard!

Pull out the mains plug before you start Always wear gloves and a dust mask of at least class FFP3 Use an extra vacuum cleaner in order to work as dust free as possible

6.3 HEPA-filter* *Only if the machine is fitted with the HEPA-filter option.

The HEPA filter should always be covered when the machine is not in use. Cover the HEPA filter in such a manner that dust, dirt and moisture cannot get inside the HEPA-filter. The easiest way is to just wrap the HEPA-filter box in plastic stretch foil. Use tape to ensure the stretch foil stays in place. An efficiency test of the dust collector must be performed at least every 12 months, which include: -HEPA-filter must be replaced if the efficiency of the filter element is not adequate (leakage test performed with a photometer), or if the airflow of the machine is reduced to 75% of the factory value due to clogging of the filter(s). -Testing that the maximum permissible filter surface load of the placed filter is not exceeded. -An electro technical safety test, performed by a competent person. (NEN 3140 or something similar. Check the national regulations.)

6.4 Pulse system

The Dust collector is provided with an air pulse cleaning system which increases the life of the filter cartridges and ensures a constant suction power. The system works by use of pressurized air, built up by a compressor The cooled air passes a control valve, which regulates the systems pressure , and then builds up pressure in the pulse tank. Normally the pressure in the system lies between 6 and 7 bar. The control valve is activated above 7 bar. The safety valve mounted on the compressor is activated at approximately 10 bar. This provision is to ensure that when there is a defect in the Control valve, the pressure in the pulse tank remains within safe limits. If the pressure of 6 bar is not reached, it is possible that either there is too much water in the pressure tank or the air filter of the compressor is dirty. If inspection of the compressor and draining of the pressure tank shows no abnormalities, it is possible that either there is a leakage in the air tubing, or the control valve is defect. In that case replace the defective parts or have it checked by Blastrac. When there is pressure but the pulse system does not function, there might be a problem in the electrical system which controls the pulsing system. Check the wiring and the PLC-settings.

Advised is to take contact with Blastrac Support in order to prevent operational problems.

6.5 Compressor

Replacement or cleaning of the air filter of the compressor is depending on the environment in which the dust collector is operating. Unscrew the cap and take out the filter inside. Clean or replace if necessary.

6.6 The V-belt

The V-belt drive is designed for the installed driving power. To force a higher output through an excessive high tension of the V-belt will result in broken belts, damage to the bearings and causes loss of the total efficiency. Too low belt tension will cause slipping with the result of a very high temperature of the V-belt and a premature destruction of it. Temperatures over 70 for a longer period will decrease the working life and the efficiency of the V-belt. The grooves of the V-belt pulleys must be free of rust, fat and dirt and must not show any damages. The use of belt wax or similar substances in order to increase the friction coefficient is not necessary and it damages the V-belt. Soiling due to oil, grease or chemicals have to be avoided. In order to get perfect power transmission the V-belt drive has to be checked every 3 months.

6.7 V-belt mounting

Reduce the distance between the driving motor and the bearing to release the tension of the V-belt drive.

Carefully put the V-belt in the grooves of the V-belt pulley by hand and without using the force.

Increase the distance between the driving motor and the bearing to stretch the V-belt as following

described.

Fix the required driving gear guards.

6.8 V-belt tension

The correct V-belt tension is of utmost importance in order to obtain a perfect power transmission and to reach the usual working life of the V-belt. Too low or to high tension causes frequently a premature breakdown of the V-belt. Excessive belt tension results in damaged bearings at drives. Check the tension of the V-belt by pressing the thumb on the belt. The belt has the correct tension If you can press it in about 10-15 mm at approx. 10 kg. pressure.

Remove the belt guard only when the driving motor is in standstill and the power

supply cable of the machine is disconnected from the power source.

7.2 Difference vacuum gauge

A vacuum gauge measures the difference between the under pressure above the filters and inner filter house. This readout indicates the degree of pollution of the filters, with this system you can always keep an eye on the condition and pollution of the filters inside the dust extractor. It can also help you fine-tune the airflow when precise adjustment is required for the job.

IMPORTANT NOTES:

The indicated values are measured on new machines. Noise levels will vary in different circumstances. Area influences like open outside or closed inside space, ambient temperature, different surfaces to be treated, daily use, different tools or accessories, poor maintenance, etc. will give different values at all time and could increase the exposure level over the total working period. The declared noise emission level represents the main application of the machine. The values may be measurements from a representative sample of technically comparable machinery. The values may be used for a preliminary assessment of exposure. A precise estimation of the level of exposure to noise should also take in account the fact that the dust collector does not require constant operating. Most of the times the operator wont be near the machine during normal activities. This may significantly decrease the exposure level over the total working period.

25

Identify additional safety measures to protect the operator from the effects of noise such as: proper and regular maintenance of the machine and the accessories, provision of proper ear protection and organization of work patterns for example by using rotation schedules. Always use ear protection when working with this machine.

Old equipment contains valuable materials which are valuable for re-processing. The machine parts must

not be thrown away in the normal household waste, but should be disposed of at a suitable proper collection system, e. g. via your communal disposal location. This way the materials can be re-used in an environmentally responsible manner.

Despite the fact that this guide is made with care, Blastrac takes no liability for errors in the manual and the possible consequences. We are naturally very interested in your findings and additions.
