Two-in-one oil coalescing filters with supreme energy savings
UD+ filters efficiently reduce oil aerosol, wet dust and water drops in your compressed air stream to protect your investment, equipment and processes. The UD+ combines two filtration steps (DD+ and PD+) into one, a unique technology to meet the high-quality requirements of diverse applications and provide ultimate energy savings.
YOUR BENEFITS
40% energy savings
A 40% lower pressure drop than the conventional filter combination results in 40% higher energy efficiency.
Pure air
Air purity is equal to that obtained using two filters in line, thanks to the thick filter package of UD+ filters.
Save space
The two-in-one filtration concept reduces installation space and complexity, making UD+ filters particularly suitable for applications where space is at a premium.
Save money
Install UD+ filters to enjoy significant cost savings compared

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 45+: 45 l/s * 0.65 = 29 l/s => the 45+ filter size is not large enough.
- Size 60+: 60 l/s * 0.65 = 39 l/s => the 60+ filter size is the size to select.
Options
• Filter connection kit for easy mounting in series (9-550 l/s).
• Wall mounting kit simplifies installation (9-550 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 size 9 + - 550 + , 850 + T and 1100 + T; standard on size 550 + F and larger).
Certification
• ISO 8573-2:2007
• ISO 12500-1:2007
