DOP Testing and Servicing

At Beacon International we have the expertise to service and D.O.P. all makes of asbestos removal equipment.
All Negative Pressure Units and “H” Type Vacuum Cleaners MUST be D.O.P. tested:

1. Every six months whether they have been used or not.
2. If the machine has been dropped or damaged in any way.

Our philosophy is that just testing a machine is not enough. At Beacon International we offer comprehensive service facilities.

Transport

Collect and return service is available covering the whole of England and Wales.

Service records

Your machine will be booked into our customer database from which we will generate a service report, test certificates and service reminders. Each service carried out becomes a permanent record on our system where we store test results, customer and plant details. Replacement certificates can be generated should you loose the originals. A service reminder will be sent to you approximately three weeks before the next service is due.

Decontamination

Every machine goes through our purpose built decontamination unit where it will be thoroughly cleaned, bags and pre filters will be replaced as required and the H.E.P.A. filter will be visually inspected. Once the machine has fully decontaminated, motors and internal wiring will be checked.

Testing
Finally every machine is:
DOP TESTED (Dispersed Oil Particulate)
This will confirm that there are no leaks in the HEPA filter or the seals inside the machine.
P.A.T. TESTED (Portable Appliance Testing)
This checks that there is an earth bond.
AMPERAGE TESTED.
Gives you an amperage reading, which lets you know which size transformer you will need.
AIRFLOW TESTED (NPU)
We can determine if your HEPA filter is blocked from this test.
VACUUM TESTED (Vacs)
The amount of vacuum created tells us if your HEPA filter and support bags are in good order.

Our engineers will advise you of blocked HEPA (High Efficiency Particle Arrestors) Filters which potential can burst as illustrated to the right.

On site testing

In some cases it is not possible for equipment to be returned to Beacon. We offer on site testing where we will carry out the same tests as in the workshop, on site repairs cannot be undertaken as stated in working with asbestos regulations. available at request.

Our engineers will test your equipment on site, any failures should be returned to Beacon for repair. 
Please note in order us to test machines on site, clean paper bags MUST be fitted to Vacuum Cleaners and clean pre filters MUST be fitted to NPU’s before they are released from the enclosure.
