Frequently Asked Questions

How do I choose the filtration degree for an irrigation filter?

Match the filtration degree to the emitter: drip irrigation needs 120 mesh (~125 micron) or finer, micro-sprinklers typically 80–100 mesh. HJLYGL disc filters are available in 40–300 mesh to match your water quality and emitters.

Manual or automatic backwash disc filter — which one should I choose?

Choose a manual backwash disc filter for cleaner water and smaller systems. For high-silt or algae-laden sources, large farms or unattended operation, the HJLYGL H-type automatic backwash disc filter system is recommended, with differential-pressure and timed control modes.

Which filter type fits my water source?

For well water with high sand content, combine a hydrocyclone sand separator with a screen or disc filter. For surface water (reservoir, pond, river) rich in organic matter, use sand media or disc filters as the primary stage. We provide free selection proposals.

Do you support OEM/ODM?

Yes. With 14 years of export manufacturing experience, we offer OEM branding and ODM customization including logo, packaging, port sizes (1"–4") and filtration degrees.

What is your MOQ and lead time?

Sample orders are welcome. Common models are in stock and usually ship within 7–15 days, depending on order quantity and customization requirements.

How long is the warranty?

A 10-year warranty applies under normal operating conditions, with long-term technical support and spare parts (filter elements, seals) supply.

Which countries do you export to?

We export to Indonesia, Thailand, Malaysia, Vietnam, UAE, Saudi Arabia, Egypt, Canada, the USA and more, with worldwide shipping and customs documents (CO, Form E, etc.).
