Annual element change
Change DFD, PFD and HFD elements at least once a year, or sooner when the pressure drop across the filter reaches about 350 mbar (5 psi). Change CFD carbon elements at least every 6 months.
After a desiccant dryer
The DFD element catches the fine desiccant dust a regenerative dryer sheds, so it does not reach valves, cylinders and instruments.
Workshop and plant air
Line filters sit after the compressor, receiver or dryer to keep water, oil and dirt out of air tools, valves and cylinders.
No. It is an aftermarket compressed air filter element made to replace the Deltech DFD540. It is not made by or affiliated with Deltech or SPX, and the part number is used only to show what it replaces.
It replaces the element marked DFD540. Check the code printed on the old element, or measure it: this one is 118 mm (4-5/8 in) in diameter and 539 mm (21-1/4 in) high. The letters give the grade (DFD dry particulate, PFD general purpose, HFD high efficiency, CFD carbon) and the number is the size.
Change DFD, PFD and HFD elements at least once a year, or sooner when the pressure drop across the filter reaches about 350 mbar (5 psi). Change CFD carbon elements at least every 6 months.
Use the same letters as the element you are taking out. A typical line runs PFD then HFD after the compressor, CFD after that when oil vapour and odour must be removed, and DFD after a desiccant dryer to stop dust.
Change the other elements in the same line at the same service, fit new O-rings if the old ones are flattened or cracked, and check that the drain on the filter bowl works.
