Middle Size Filter

Product Overview

The middle-size filter is a compact pre-treatment unit that sits between the large and small filter models in the drinking line range. Model SL-02, it pairs a blue upper cap with a short transparent cup and a white cartridge inside, while the two connection ports are finished in red barbed hose tails. With a port outer diameter of 25 mm, it matches the standard main drinking line hose used in most poultry houses.

At 240 mm long and 550 g per piece, this unit is light enough to hang directly on the line without heavy support, and 60 pieces fit into one export carton, which keeps wholesale freight efficient. A black metal mounting bracket with fixing screws is supplied on top of the cap, giving installers a firm fixing point on the house wall or the water manifold. The middle capacity suits farms that find the small filter too restrictive but do not need the large cup for their flock size, and it is a common first upgrade for houses that previously ran no filtration at all.

Key Features and Benefits

• Balanced middle capacity - the 240 mm body gives enough flow for a single drinker line without the bulk of a large cup.
• Red barbed ports - the bright red tails push onto 25 mm hose and are easy to spot during maintenance.
• Metal mounting bracket - the black steel bracket with screws holds the filter steady against line vibration.
• Transparent cup - the clear housing lets the farmer check cartridge dirt level at a glance.
• Light weight - at 550 g per piece, handling and on-site installation are quick for one worker.
• 60 pieces per carton - the high packing density lowers shipping cost per unit for distributors.

Materials and Quality

The cap and cup are molded from the same engineering plastic used across the filter range, chosen for smooth water contact and good visibility of the cartridge. The red barbed tails are molded in one piece with the cap, so there is no glued joint that could loosen under pressure. The black mounting bracket is a formed steel plate fitted with screws, giving a sturdier fixing than a plastic bracket on a vibrating line. Each unit is leak-checked before packing, and the 60-piece carton is designed to keep the long transparent cups from rubbing against each other during transport. The bright red ports also serve as a quick visual marker for service teams, since the color makes the connection points easy to find in a dimly lit house.

How to Use and Maintain

Fix the black bracket to a wall or frame with the supplied screws, slot the filter onto it, and push the 25 mm hose over the red barbed ports. When the transparent cup shows noticeable sediment, close the inlet, twist the cup off by hand, and rinse the white cartridge under running water. Reassemble with the sealing ring seated flat, then slowly reopen the water to avoid a sudden pressure surge. For flocks on well water with heavy silt, a weekly rinse is recommended; for cleaner municipal water, biweekly rinsing is usually sufficient. Keep the spare sealing ring in the maintenance kit, because a worn ring is the most common cause of small leaks around the cup.

Applications

This middle-size filter suits small and medium broiler houses, layer sheds and pullet rearing farms where one header line feeds a single row of nipple drinkers. It is also a common choice for backyard breeder setups and duck or goose sheds that need basic water pretreatment without the cost of a large industrial filter, and it fits neatly alongside a pressure reducing tank in a standard house header.

Distributors value it as a flexible stock item, because the 25 mm ports fit most standard lines and the compact size sells well to farmers upgrading from no filtration at all. It can be combined with pressure reducing tanks and hose reels to build a complete drinking line kit for new projects, and its compact size makes it a popular replacement part when an older filter develops cracks.
