Frequently asked questions

Is this a genuine Bea ARS-180 RB?

No. It is an aftermarket compressed air filter element made to replace the Bea ARS-180 RB. It is not made by or affiliated with Bea, and the part number is used only to show what it replaces.

Will it fit my machine?

It replaces the element numbered Bea ARS-180 RB and the other numbers in the cross reference table. Check the number on the old element or in the machine's parts list, or measure it: this one is 170 mm (6.69 in) high.

When should I change the element?

Change the element at least once a year, or sooner if the differential pressure gauge on the housing shows it is loaded.

How do I fit it?

Isolate the filter housing and let the pressure out. Unscrew the bowl, pull the old element off its seat, fit the new element with its O rings lightly lubricated, refit the bowl and pressurise slowly. Check for leaks.

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.
