The standard needlefelt drainage layer has a high thermostability (up to 120 °C) compared with the foamed plastic used in other filter products. It is also chemically and mechanically highly resistant and free of silicone. Combined with the reliable construction, the filter element is absolutely safe against a blow-up or damage of the drainage layer. A continual use of the whole filter surface is thus realised.

The closing mechanism is a safety feature that allows 100 % control during opening of the filter housing. If the housing is opened while still under pressure, an audible warning signal will be given.

Condensate from compressed-air filtration is nearly always aggressive, so that unprotected housings would be exposed to corrosion. CLEARPOINT filter housings are made of seawater-resistant aluminium and are additionally anodised inside. This offers increased corrosion protection, while the permanently smooth surface also reduces the flow resistance.

With an extremely high void volume of 96%, the boron silicate filter material ensures that the pressure loss is kept to a minimum. Conventional filter material of sintered polyethylene only has a void volume of 45%. With CLEARPOINT filters, the cross-sectional area available for flow is therefore more than twice as large.

By the way, conventional filter media are often hydrophilic, so that the fibres will swell up and reduce the void volume. The filter then becomes clogged, the pressure loss increases, and so do the operating costs. By contrast, the material of CLEARPOINT filter elements is impregnated as a standard. This prevents swelling up of the filter material, permits a steady differential pressure, and avoids unnecessary expenditure.

CLEARPOINT filter elements are installed without tie-rods so that the cross-sectional area is fully available. This reduces the flow resistance, while the space required for element replacement is only about one third compared with other designs - a great advantage under spatially restricted conditions. Thanks to the innovative push-fit design of the filter elements, replacement is very fast and simple. The element is held securely in a leak tight position by an O-ring seal at the top cap and three supports at the bottom of the housing.

Highly economical! The flow optimised inlet into the filter element reduces flow resistance up to 75%.

The threaded connections of the CLEARPOINT compressed air filters are generously dimensioned in comparison to other filters on the market. They are especially matched to the typical pipe diameters of various compressor brands, thus eliminating energy consuming pipe reductions. When combining two or more CLEARPOINT filters, the innovative connection keeps up the fill diameter flow.
