1. Low backpressure improves energy efficiency
2. 99% of the expelled oil is captured and returned to the system, making fewer oil refills necessary
3. Fine filtration material fills slower than a conventional filter, extending changing intervals

1. Cleaner air
2. Reduced noise level
3. Lower temperature in the pump’s vicinity

1. No negative impact on ultimate pressure throughout the filter’s lifetime
2. Minimum flow resistance reduces load on the vacuum pump
3. Stable filtration performance, whatever the application

SIGN OF QUALITY

Busch genuine exhaust filters are all subject to comprehensive testing during production. Each has its own signature of origin, making it fully traceable.

This gives you the security of knowing that you are using exclusively genuine Busch parts – and that you are maintaining your product warranty.

HOW OIL FILTRATION WORKS

Only Busch genuine exhaust filters deliver the best results. Several layers of an ultra-fine filtration material trap and collect the oil mist as it passes through the exhaust filter. The filtration medium combines exceptional performance with the highest possible separation levels.

The oil particles coalesce on the interior of the filter element and are recycled back into the vacuum pump. Oil emissions to the ambient air are therefore reduced to an absolute minimum. This keeps backpressure low and leads to greater energy efficiency due to minimized flow resistance.

TECHNICAL BENEFITS OF BUSCH GENUINE EXHAUST FILTERS

Filter backpressure

Conventional filter materials and designs (black line) fill with oil faster than a Busch genuine exhaust filter (orange line). The filter backpressure increases rapidly, which leads to a decrease in air flow through the exhaust.

A conventional filter also reaches its maximum permitted backpressure after a lower number of operating hours. As a result, they have a shorter service life and need to be changed more frequently.

Oil mass carryover

The ultra-fine filtration medium and tight mesh in Busch genuine exhaust filters (orange line) catch more oil than conventional filter materials and designs (black line). This means significantly lower oil mass carryover at all operating pressures and a cleaner working environment.

THE RIGHT EXHAUST FILTER FOR EVERY APPLICATION

Busch genuine exhaust filters provide excellent filtration whatever the application and fully comply with all emission standards.

They are suitable for oxygen-rich applications and have high tolerance to harsh chemicals. Their highly conductive design prevents the risk of ignition through electrostatic discharge. For processes in explosion hazard areas, special exhaust filters suitable for ATEX-certified vacuum pumps are available.
