Testing:

Equipment Performance

Robertson Air Systems consistently verifies equipment performance prior to start-up as follows:

1. Current readings on all three legs of the fan motor--the current readings help verify the blower performance and confirm safe motor operation.
   
2. Air flow in CFM determined by a pitot tube traverse (5 readings in two directions) with a manometer within an inlet test pipe.
   
3. System air pressure readings (in inches of water column) at various locations within the air handling equipment.
   
4. Six DBA sound pressure readings taken 5' above the ground at a 10' distance all around the equipment.

The above testing services are also available upon request on all bus vacuum systems.

Emissions

Robertson Air Systems employs our expertise in air quality testing and assisting facilities to achieve a clean air environment in the bus vacuum system work area. We have conducted extensive tests using a Staplex sampler that have verified that most bus vacuum system emissions particles are bus exhaust soot. The exhaust soot is drawn into bellows during vacuuming as busses idle and accelerate through the work area.

We are a leader in technology developed to minimize bus vacuum system exhaust emissions. Atomized misters, effective sealing systems, stack dampers, exhaust locations, and the use of super efficient cyclone separators are all design features that contribute to a dust-free work area.
