Oval air filter cartridge to replace Donaldson original filter with ultra web

Mr Ninh from Vietnam sent us inquiry for the oval air filter cartridge for their factory dust collector.

We know the filter is from Donaldson. And the original filter media is Ultra web.

Till now only Donaldson has such patented filter media and its performance is really nice.

However, we have replaceable filter media – polyester with ptfe membrane.

And both our domestic and overseas customers have used it in their device. Certainly the performance

is very good(but to be honest will be a little bit inferior than ultra web).

We told Mr Ninh the reality and sent him the technical data. He decided to buy 4pcs to have a try

on 21st November. And we finally made delivery on 3rd December, 2019

And today Mr Ninh gives his appreciation on our products. Thank you so much for your trust and

best wishes for you and your families for the New year.

Welcome to send us inquiry on various air filter cartridges.
