Easy Clear Cartridge Filter (Last Sold 2022 / 2024) exploded view & spare parts

Davey Easy Clear Cartridge Filter (39100EU / 39150EU) exploded view & spare parts

This page covers the complete exploded-view diagram and bill of materials for the Davey Easy Clear Cartridge Filter sold under factory references 39100EU (100 sq ft) and 39150EU (150 sq ft). These filters were last sold new in 2022 and 2024 respectively, and genuine spare parts remain available for both sizes. The diagram shows every serviceable component — from the air bleed assembly at the top of the lid down to the reinforcing ring at the base of the tank. Whether you are a pool owner carrying out routine maintenance or a technician replacing a failed part, you should be able to identify exactly what you need within a few minutes using the numbered diagram and the parts list below.

Cómo utilizar el esquema numerado para localizar tu pieza

Every number printed on the diagram corresponds directly to a row in the parts list table; locate the component on the diagram first, note its position number, then find that number in the table to retrieve the correct SKU. A practical approach is to work by area: start at the top of the filter (lid and air bleed assembly), move down through the tank body, and finish with the plumbing connections and base hardware. Be aware that position 7 and position 8 each appear twice in this diagram — once for the 100 sq ft model (39100EU) and once for the 150 sq ft model (39150EU) — so you must confirm your model reference before ordering either the cartridge element or the filter body. Similarly, position 11 (Cartridge Support Assembly) is size-specific: the two variants carry different SKUs and are not interchangeable between the two tank sizes. If a position number points to a small fastener or sealing component that appears in more than one location on the diagram, check the written description carefully, as one SKU may cover a set or kit rather than a single piece. When in doubt about which variant applies to your unit, the model reference (39100EU or 39150EU) is usually printed on a label affixed to the filter tank body.

Main replaceable assemblies on the Davey Easy Clear Cartridge Filter

El lid assembly is the most frequently accessed part of the filter. Position 6 (SKU: 33203SP) supplies the complete filter lid together with its O-ring, making it a convenient single-item replacement when the lid itself is damaged or when the seal is beyond simple re-greasing. The lid is secured by the lock ring at position 3 (SKU: Q2334YSP), which allows tool-free removal for routine cartridge cleaning. At the very top of the lid sits the air bleed screw (position 1, SKU: Q2033SP) together with its dedicated Junta tórica (position 2, SKU: Q2034SP); these are the first components to replace if you notice air being drawn into the system or a persistent drip from the bleed point. The pressure gauge at position 5 (SKU: 49091SP) is an oil-filled, bottom-mount 250 kPa unit fitted to the lid; it is the visual indicator that tells you when the cartridge element needs cleaning, so a fogged or seized gauge should be replaced promptly. The cartridge element at position 7 is the core filtration medium — SKU Q2312 for the 39100EU and SKU Q2313 for the 39150EU — and is the part most owners replace on a seasonal or annual basis. Beneath the element, the cartridge support assembly at position 11 (Q2342SP for 39100EU; Q2343SP for 39150EU) holds the element in correct alignment inside the tank. The filter body at position 8 (Q2322SP or Q2323SP depending on size) is the main ABS tank shell. Completing the hydraulic connections, position 9 (SKU: 33204SP) provides the 50 mm barrel union set for connecting to pool pipework, while the blanking cap kit at position 10 (SKU: 32937) is used to seal whichever of the two inlet ports is not in use. The reinforcing ring at position 12 (SKU: Q2386SP) supports the structural integrity of the tank base and is worth inspecting whenever the body is removed for a deep service.

Choosing between variants and pack sizes

The most important variant decision on this filter is model size: the 100 sq ft (39100EU) and 150 sq ft (39150EU) versions share many common parts (positions 1–6, 9, 10, 12), but positions 7, 8, and 11 are unique to each size and must be ordered to match the model reference on your tank. Ordering the wrong cartridge element or support assembly is the single most common mistake — the 150 sq ft element (Q2313) is physically longer than the 100 sq ft element (Q2312) and will not seat correctly in the smaller body. For the lid O-ring (position 4, SKU: Q2231SP), confirm the seal is seated cleanly and undamaged before assuming the lid assembly (position 6) needs full replacement, as the O-ring alone is the more economical first step. The barrel union set at position 9 is supplied as a set for the 50 mm EU plumbing standard; ensure your existing pipework matches this diameter before ordering, as forcing mismatched unions can stress the tank inlet boss.
