High performance oil coalescing filters

DD(+) and PD(+) filters efficiently reduce oil aerosol, wet dust and water drops in your compressed air stream. These could come from the lubrication of the compressor element, the intake air, and the compressor installation itself. These innovative filtration solutions are engineered to cost-effectively provide the best air purity and meet today’s increasing quality demands.

YOUR BENEFITS

Maximum oil aerosol, wet dust and water droplet filtration and drainage

High-efficient glass fiber and foam media.

Significant energy savings & limited system operating costs

Optimal design and filter media allow low pressure losses.

High reliability

High-performance stainless steel cores, double O-rings, epoxy sealed caps, and anti-corrosive coated filter housing.

Easy maintenance

External ribs on the threaded housing, or a rotating bottom cover for the welded housings, and push-on elements.

Monitoring of energy use

Differential pressure indication (indicator for sizes 10-35 l/s, gauge for sizes 50-8000 l/s) (optional for standard range).

Example

• Working pressure 3 bar(g), compressed air flow 35 l/s.

• Multiply the nominal capacity of the selected filter with the corresponding correction factor at the required working pressure to obtain the capacity at working pressure:

- Size 50+: 50 l/s * 0.65 = 33 l/s => the 50+ filter size is not large enough.

- Size 70+: 70 l/s * 0.65 = 46 l/s => the 70+ filter size is the size to select.

Options

• Filter connection kit for easy mounting in series (10+ - 550+ l/s and 12-690 l/s).

• Wall-mounting kit simplifies installation (10+ - 550+ l/s and 12-690 l/s).

• Quick coupling connects the filter with a drain or oil/water separator.

• Voltage-free contact mounted in the differential pressure gauge, to give remote indication of cartridge replacement.

• EWD electronic drain with no loss of compressed air and an alarm function

(EWD is optional on sizes 10+ - 550+ l/s and 12-690 l/s; standard on sizes ≥550F).
