Start your enquiry.

Share a few details so we can review your requirements. Fields marked * are required.

How we can help

Support for the decisions behind your order.

Whether you are sourcing a new filter or reviewing an existing installation, start with the information you have.

Product selection & quotations

Discuss high-flow, pleated, membrane or depth filter cartridges, as well as liquid filter bags. Tell us your application, preferred media, filtration rating and order quantity so we can review the specification with you.

Replacement cartridge matching

Share the current brand and model, cartridge dimensions, end connections and housing details. Clear photos of both ends help us review the interface and identify which details need confirmation before ordering.

Samples & trial requirements

Planning a fit check or an application trial? Tell us the product specification, sample quantity and what you want to evaluate. We can discuss sample arrangements and the information needed for your trial.

Technical & after-sales support

For a compatibility question or a differential-pressure issue, include the product model, operating conditions and a description of what changed. For an existing order, add the order reference and relevant photos.

Before you enquire

A few practical answers.

You do not need a complete specification to start a conversation. Share what you know, and tell us what still needs to be decided.

Can I enquire without a model number?

Yes. Describe your liquid and process, and share the dimensions, filtration rating or housing information you have. Photos or a drawing can help us clarify the missing details.

Can I send photos and technical drawings?

Yes. Send them directly to our email or through WhatsApp. If you use the enquiry builder above, attach the files after opening the draft in your email app.

What should I include for a delivery enquiry?

Include the product specification, quantity, destination and your requested delivery date. These details give us a starting point for discussing the order and shipping arrangements.
