Backwash Filter

Product Overview

The backwash filter is a pre-treatment unit installed on the main water line of a poultry drinking system, designed to remove sediment, rust particles and debris from source water before it reaches the nipple drinkers. Model SL-03, this unit combines a white upper manifold with a transparent filter cup and a yellow sealing ring, so the operator can see the water level and the amount of collected dirt at a glance. The side connection ports measure 25 mm, matching the common main pipe diameter used in broiler and layer houses.

A distinctive feature of this design is the backwash function, operated through the red drain valve at the bottom of the cup. Instead of unscrewing the housing for every cleaning cycle, the operator can open the valve and let a reverse flow rinse the cartridge, flushing trapped particles out through the drain. The whole unit stands 220 mm tall with a 160 mm cup diameter and weighs about 1040 g, while each export carton holds 20 pieces, making it easy to stock and ship in container quantities. Because it sits close to the pressure reducing tank, this filter protects the whole downstream line, including small nipples, hinges and drinker cups that are sensitive to clogging.

Key Features and Benefits

• Backwash rinsing - the bottom drain valve lets operators flush the cartridge without disassembling the cup, shortening daily maintenance time.
• Transparent sight cup - the clear housing with a yellow ring shows accumulated dirt and water condition, so each inspection takes only a few seconds.
• 25 mm inlet and outlet - the ports match standard main water pipes in poultry houses for a direct push-fit connection.
• Internal white filter cartridge - the cartridge with yellow bands captures suspended particles before they enter the nipple line.
• Economical packing - at 20 pieces per carton and 1040 g per unit, the freight cost per house stays low for distributors.
• Compact footprint - the 220 mm height fits in limited space beside the pressure reducing tank or the main water inlet.

Materials and Quality

The housing and manifold are molded from engineering plastic with a smooth surface, while the transparent cup is formed to resist the daily water pressure seen in a farm environment. The yellow twist ring and red drain valve follow a clear color code, which helps workers identify the operating parts quickly during routine checks. Every unit is visually inspected and leak-tested before shipment, and the export carton is lined to protect the transparent cup from scratching during transport. The plastic used for the housing is chosen for stiffness and impact resistance, so the cup keeps its shape even when dust, feed and small birds bump against it inside the house.

How to Use and Maintain

Connect the filter into the main water line between the source and the drinking line, following the flow direction indicated on the housing. When the transparent cup shows a visible layer of sediment, open the red bottom valve and let the backwash flow carry the debris out for a few seconds, then close the valve. For a deeper clean, unscrew the yellow ring, take out the cartridge and rinse it with clean water; replace the cartridge if it is torn or heavily stained. Check the sealing ring for aging once per season, and make sure the valve closes tightly after each rinse so no water drips onto the house floor.

Applications

This filter is widely used in broiler houses, layer houses and breeder farms where well water or municipal water carries silt, sand or rust. It protects downstream nipple drinkers from blockage, which directly reduces the time spent unclogging individual nipples and keeps water intake stable for the flock. Clean water also supports smoother medication and vaccine dosing through the line, because particles no longer interfere with the dosing pump.

It also works well in turkey, duck and goose farms, as well as in small livestock operations that share a common water supply. Distributors and integrators can mix this backwash filter with pressure reducing tanks, water line hoses and drinker accessories in the same container to serve a complete drinking line project.

A: The inlet and outlet ports are 25 mm, matching the standard main pipe used in most automatic poultry drinking systems.

Q2: How often should the cartridge be cleaned?

A: It depends on source water quality. Check the transparent cup weekly; when visible sediment builds up, open the drain valve for a backwash and rinse the cartridge thoroughly at the end of each flock cycle before disinfecting the line.

Q3: Can I buy spare cartridges separately?

A: Yes, replacement cartridges and sealing rings are available as spare parts; please contact us with the model number SL-03 so we can quote the matching set.

Q4: How many units fit in one export carton?

A: The standard packing is 20 pieces per carton, which helps us calculate ocean freight and mixed-container loads accurately for your order.
