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.).
How can I get a quotation?
Contact us via WhatsApp +86 156 9085 1323 or export@meijucs.com with your flow rate (m³/h), water source and pipe size; we reply with a quotation and selection proposal within 24 hours.
Which mesh should I choose for drip irrigation?
120 mesh (~125 micron) is the standard choice for most drip emitters. Use 150 mesh (~100 micron) for pressure-compensating drippers with narrow passages, and 80 mesh (~180 micron) is enough for sprinklers.
How often do I need to clean the discs?
It depends on water quality. Clean the stack when the pressure difference reaches about 0.5 bar; on typical surface water this means periodic rinsing every few weeks, and dirtier water needs shorter intervals.
Can I upgrade the manual unit to automatic backwash later?
Yes. The same grooved disc stacks are used across the HJLYGL manual, semi-automatic and fully automatic backwash series — contact us for the matching upgrade unit.
What is the difference between HJLYGLT002-1M2D and HJLYGLT003-1M3D?
HJLYGLT002-1M2D is the 2-inch (DN50) version; HJLYGLT003-1M3D is the 3-inch (DN80) version with the larger filtration area (up to 699 cm²) and the full 56 m³/h maximum flow.
Do you support OEM/ODM and custom branding?
Yes. HJLYGL is a source factory: OEM/ODM logos, custom colors, packaging and multilingual manuals are supported, backed by 14 years of export experience to 30+ countries.
The HJLYGL T-Type Manual Disc Filter Unit is a T-structure irrigation disc filter that removes sand, silt, algae and organic particles from well, river and reservoir water before they reach drip emitters or sprinklers. It combines a centrifugal water inlet with grooved disc stacks: large heavy particles are spun away from the discs first, so head loss stays low and filtration efficiency stays high. The unit is made by Henan Haojun Agricultural Technology Co., Ltd. (brand: HJLYGL), an ISO 9001 certified source factory with 14+ years of irrigation filtration export experience to 30+ countries.
【Key Features】
1. Centrifugal water inlet — spins large particles away from the disc stacks, reducing head loss and keeping high filtration efficiency.
2. Grooved disc stacks — provide both surface filtration and depth filtration; the stack rinses clean during backwash, so manual maintenance is low-frequency.
3. Corrosion-proof materials — high-strength engineering plastics resist fertilizer chemicals, UV exposure and aging in open-field conditions.
4. Three interchangeable filtration grades — 80 mesh (about 180 micron, green), 120 mesh (about 125 micron, red) and 150 mesh (about 100 micron, orange) discs fit the same body.
5. T-shape body — male thread, clamp or flange connection; installation and stack removal take minutes without special tools.

【Disc Filter vs Screen Filter — When to Choose Which】
- Organic matter (algae, slime, root fibers): the disc filter is the better choice — the grooved stack catches soft and fibrous particles through its full depth, while a screen clogs quickly.
- Hard sand from wells: both types work; placing a HJLYGL hydrocyclone sand separator in front of the disc filter extends backwash intervals.
- Very fine silt (below 100 micron): choose 150 mesh discs and expect more frequent rinsing.
- Budget-critical small systems: screen filters cost less upfront; disc filters pay back through lower cleaning frequency and longer service life.
【Typical Applications】
- Drip irrigation and micro-sprinkler systems in orchards, vineyards and open-field vegetables
- Greenhouse fertigation lines, protecting emitters from fertilizer precipitates
- Garden, landscape and nursery irrigation
- Final protection stage after sand media filters or hydrocyclone separators
【Installation & Maintenance】
Install the unit after the pump with the flow direction arrow matching the water flow. Rinse the disc stack when the pressure difference across the filter reaches about 0.5 bar: unscrew the cartridge, open the stack, rinse with clear water and a soft brush, then reassemble. Discs are color-coded by grade, so changing the filtration grade takes under one minute. No lubricants or special tools are required.
