Jandy DEV 48 SqFt Diatomaceous Earth Filter

The Jandy DEV48 is a diatomaceous earth (DE) filter built for residential pools that demand ultra-fine filtration. It uses a curved-grid internal design to evenly distribute flow throughout the tank, capturing particles down to around 5 microns for exceptionally clear water. The rugged composite tank is highly resistant to corrosion and UV exposure, and the filter supports a variety of valve options to suit your plumbing setup.

Features

• Curved vertical grid pack for balanced flow distribution.

• Captures debris as fine as 5 microns for very high filtration quality.

• Heavy-duty composite tank that resists UV and corrosion.

• Easy-grip handles make removing the lid more convenient.

• Large 2″ drain port for effective debris and water purge.

• Built-in gauge + manual air release, with a clean / dirty indicator.

• Versatile valve compatibility: works with multiport, slide, or Never‑Lube® valves.

• Composite clamp ring keeps the tank tightly sealed and serviceable.

Benefits

• Superior Water Clarity: DE filtration can catch much smaller particles than sand filters.

• Longer Cycles: The large grid area holds more DE and dirt, reducing how often you need to backwash or clean.

• Durable Construction: Composite body resists environmental wear and pool chemical corrosion.

• Easy Maintenance: Large drain and convenient access via lid make cleaning straightforward.

• Flexible Setup: Use whichever valve works best for your existing plumbing.
