Precision Duty 88342977 Pneumatic Pre Filter for Laser Optics Electronics Assembly

Product Description

Product Description

Precision Oil Removal Compact Pre Filter Element – Model 88342977

The 88342977 is a compact pre filter cartridge designed for critical point of use applications requiring both particulate and oil mist removal. Its 53 mm diameter and 78 mm height house micro fiberglass depth media that captures solid contaminants down to 1 micron while simultaneously reducing residual oil content to 0.5 ppm — a unique dual performance not found in standard dust-only filters. This element is ideal for laser optics protection, electronics clean assembly, sensitive instrumentation, and any process where oil-free compressed air is essential.

Rated at 0.53 Nm³/min, the 88342977 serves single high precision devices, fine sandblasting nozzles, or laboratory equipment. The integrated oil removal capability eliminates the need for a separate coalescing filter in many low flow applications, saving space and cost. Clean pressure drop is ≤0.01 bar, delivering 5-7% energy savings over the 8000 hour service life. Weighing only 0.1 kg, replacement is quick and tool-free.

This element excels where both dust and oil vapor must be controlled but flow demand is modest. Typical placements include laser cutting head assist air final protection, electronics pick-and-place vacuum lines, precision sandblasting of delicate parts, and medical or analytical instrument air supplies.
