OBS/P.
OBS/P Stationary balancing exhaust extractors are designed for the extraction of exhaust fumes emitted by a vehicle’s exhaust pipe during engine tests, adjustment and diagnostics. They are used in bus depots, garages and car service stations. The unit can be mounted on a wall or a column. The unit can work with a fan fixed on a wall bracket or roof fan or as part of a centralised extraction system. The built-in shut-off damper allows the use of a smaller fan where multiple units are installed but not all used at the same time.
