Benefits

Blower Assisted Exhaust (BAE) units are the perfect solution for eliminating oil leaks through driveshaft seals in crankcases and oil reservoirs along the drive train of large gas and steam turbines, compressors, turbo compressors and reciprocating engines. The BAE runs continuously to provide 3 functions to support your machinery. The main function is to create and maintain a vacuum in the crankcase or reservoir to eliminate oil leakage through the driveshaft seals. Secondary functions include the ability to coalesce oil mist while returning oil through a drain line to the reservoir and provide oil free, environmentally friendly exhaust.

Major System Components

Regenerative Blower**:
Each system requires a different amount of vacuum in its housing to prevent oil leakage through the seals around the drive shafts. The vacuum is created by a regenerative blower. A blower system is sized for each application according to the cubic volume of the housing and leakage rates of the seal.

Coalescing Filter Element:
Due to the turbulent oil flow and the temperature inside the oil reservoir, oil mist droplets will be entrained in the air stream created by the blower. This oil needs to be removed before it is exhausted to atmosphere, where it would cause environmental damage. The coalescing element not only removes the oil but collects it in a droplet form and then deposits it in the bottom of the filter housing. The collected oil is drained back to the oil reservoir, reducing oil loss and maintenance to the system.
