Filters should be inspected, cleaned and/or replaced every 500 hours.
Can units be used for pressure or vacuum?
Rotary vane units can be used for either vacuum or pressure except for separate drive lubricated models which are designed to be model specific for vacuum only or pressure only.
Can all separate drive units be pulley driven?
All separate drive units may be pulley-driven with the exception of the 67 series which require a 56C NEMA frame motor and must be direct coupled.
What is the general speed for a separate drive unit?
