How often should I replace the exhaust mist filter?

Typically every 2,000 hours or whenever oil mist is visible at the exhaust. A saturated exhaust filter is a common cause of higher-than-baseline oil consumption.

Are bearings replaced at every service?

Bearings are usually only replaced as part of a major overhaul (8,000–16,000 hours), or sooner if bearing noise develops. Routine minor services don't typically include bearings.

Do you supply 0.2 µm bacterial filters for hospital CMVS pumps?

Yes — inline 0.2 µm bacterial filters and bacterial filter housings for HTM 02-01-compliant medical vacuum systems.

Filters & Bearingsfor Vacuum Pumps

Inlet filters, oil filters, exhaust mist eliminators, and bearings for every major vacuum pump brand. Coalescing exhaust filters, sintered inlet filters, oil filter cartridges, and pump and motor bearings. Next-day UK delivery.

What are filters & bearings?

Vacuum pump filters protect the pump from inlet contamination and remove oil mist from the exhaust; bearings support the rotating shaft. Both are routine wear items replaced at scheduled service intervals.

What this category covers

What's included in filters & bearings

Inlet filters — sintered metal or pleated paper elements that trap particulate before the pump
Oil filters — replaceable cartridges that trap solids in circulating pump oil
Exhaust mist eliminators (coalescing filters) — coalesce oil aerosol from the exhaust gas to atmosphere
Filter service kits — pre-packaged sets containing all the filter elements + a charge of pump oil for routine 500h–2,000h maintenance. See Service Kits for the full kit-tier breakdown.
Bacterial inline filters — 0.2 µm filters for medical CMVS and pharma duty
Pump bearings — rotating shaft bearings (typically deep-groove or angular contact ball bearings)
Motor bearings — drive motor bearings, often serviced at the same interval as pump bearings

When to replace

When should filters & bearings be replaced?

Manufacturer's scheduled service interval

Oil filter every oil change; exhaust mist filter every 2,000 hours typical; bearings every major overhaul (8,000–16,000h).

Visible oil mist from exhaust port

Exhaust mist filter is saturated. Replace promptly — both for environmental compliance and to maintain pumping performance.

Bearing noise — squealing, grinding, or rumbling

Bearing failure imminent. Stop and inspect; running on failed bearings will damage the shaft.

Pressure drop across filter housing

Inlet filter clogged. Replace and investigate the source of contamination.

Signs of wear

How to spot a problem

Visible oil mist or oil droplets at exhaust port
Higher operating temperature than baseline
Audible bearing noise (squeal, rumble, grinding)
Vibration at the bearing housing
Reduced pumping speed (clogged inlet filter)

Frequently Asked Questions

Common questions about filters & bearings

Inlet filters protect the pump from particulate in the process gas — typically sintered metal or pleated paper. Exhaust filters (coalescing mist eliminators) coalesce oil mist out of the exhaust before it reaches atmosphere, both for environmental reasons and to recover oil back into the pump.
