Use cases & applications

Scheduled element change
Change particulate and coalescing elements at least once a year, or sooner when the pressure drop across the filter reaches about 0.7 bar (10 psi). Change activated carbon elements at least every 6 months, or when oil odour returns downstream.

Oil free, odour free air
The carbon stage removes oil vapour and odours for food and drink packaging, pharmaceutical, laboratory and paint lines.

Workshop and plant air
Line filters sit after the compressor, receiver or dryer to keep water, oil and dirt out of the air system.

Frequently asked questions

Is this a genuine Wilkerson MXP-95-522?

No. It is an aftermarket compressed air filter element made to replace the Wilkerson MXP-95-522. It is not made by or affiliated with Wilkerson or Dixon, and the part number is used only to show what it replaces.

Will it fit my filter?

It replaces the element marked MXP-95-522. Check the number printed on the old element or on the filter body label before ordering.

When should I change the element?

Change particulate and coalescing elements at least once a year, or sooner when the pressure drop across the filter reaches about 0.7 bar (10 psi). Change activated carbon elements at least every 6 months, or when oil odour returns downstream.

Which element do I need?

Use the same part number as the element you are taking out. A typical line runs a general purpose coalescing or particulate filter, then a 0.01 micron coalescing filter, then an activated carbon adsorber where oil vapour and odour must be removed.

Should I change anything else at the same time?

Fit a new bowl O-ring if the old one is flattened or cracked, check that the bowl drain works, and change the other elements in the same line at the same service.

Do you ship to my country?

Yes, we ship worldwide. Shipping is calculated at checkout, and every order is covered by our 30 day money back guarantee and price beat guarantee.
