How To Clean An Inlet Filter

Each Vmax system is tested and checked at the factory prior to shipment to ensure trouble-free operation. In the unlikely event you encounter a problem, we recommend that you consult with your local distributor for parts/service. Remember, when calling for service, parts or system information, always have the pump or system model number and serial number ready.

WARNING! Before attempting any repairs, disconnect all power from the system by switching off power at the main breaker or disconnect switch. Always use appropriate Lock Out – Tag Out procedures.

Some types of inlet filter elements can be cleaned and reused. However, damage can occur to an element during cleaning, so it is important that care is taken during disassembly, cleaning and re-assembly. Damaged elements can allow particulate to pass through the element which may cause oil contamination or damage to your vacuum system.

Polyester inlet filter elements can be washed in warm soapy water, vacuumed, gently blown out with low pressure air or replaced. If the element is washed in warm soapy water, make sure it is dry before it is reinstalled.

Paper inlet filter elements can be lightly blown out with low pressure air. They are disposable and in most cases should be replaced with a new element.

Some inlet filter elements are equipped with polyurethane prefilter. The polyurethane prefilter can be washed as a sponge or replaced to give the inlet filter element a longer service life.

Epoxy-coated wire mesh elements and stainless steel wire mesh elements can be cleaned like a polyester element. In addition, mild solvents may be used.

Activated carbon inlet filter elements are not cleanable and must be replaced when dirty.

Polypropylene inlet filter elements and Nomex-cloth inlet filter elements can be washed in warm soapy water, vacuumed, gently blown out with low pressure air or replaced. If the element is washed in warm soapy water, make sure it is dry before it is re-installed.

Any time you are not confident that the integrity of the element was maintained during cleaning, it is recommended that a new element be installed.

Warning! If the process air is hazardous, handle and dispose of used inlet filter elements per federal, state and local hazardous material guidelines.
