n cases where the vacuum level of the process is causing a large quantity of oil mist exhausting from
the pump, it is possible to mount the 1200120A0 filters inside of the EV-0175, 0250 & 0300 pumps.
Do not clean or re-use these filters. ilters must be disposed of in a proper way as they might

4.5 Maintenance Chart
Daily : visually check oil level and colour.
Weekly : inspect inline (inlet) filter and check oil leaks from the vacuum pump.
Monthly : check the exhaust filter function
( f oil mist at exhaust, replace the exhaust filter with O-ring).
Every 2- 6 month : drain and discard oil from pump while hot. Refill with fresh oil.
Every 9-18 month : replace exhaust filter elements with O-ring and gas ballast filter.
Every 500 ~ 2000 operating hours:
Change the oil and oil filter. n version of float valve with oil return line,
check the float valve’s operating conditions.
For motor - See the motor manufacture's manual for periodic motor maintenance.
The operating life of the pump is greatly enhanced based on the oil quality and condition of
the filters. Periodic maintenance will ensure a reliable operating vacuum pump.
