Festo 159594 LFP-D-MIDI-5M Aftermarket Filter Cartridge, 5 µm

$4.66 USD
Festo 159594, direct aftermarket replacement. Aftermarket replacement for the Festo 159594 filter cartridge, Festo type LFP-D-MIDI-5M. It fits LF-...-D-5M-MIDI filters and LFR-...-D-5M-MIDI filter regulators (5 µm grade) and is made to the same size, so it goes into the filter in place of the original.

It is the standard particle filter stage of the filter or filter regulator: it catches pipe scale, rust and dirt and, with the bowl's swirl, separates liquid water and oil droplets before the air reaches valves and cylinders. Sold as a single cartridge, shipped worldwide, and covered by our 30 day money back guarantee and price beat guarantee. TECHNICAL PROPERTIES & CROSS REFERENCES

Use Cases & Applications

Standard air preparation
Every Festo D series filter and filter regulator carries one of these cartridges as its main particle filter.

5 µm or 40 µm grade
Use the 40 µm grade for general plant air and the 5 µm grade in front of valve terminals or a fine filter.

Pre-filter for fine and micro filters
A clean standard cartridge ahead of an LFMB or LFMA stage makes the finer cartridges last longer.

Planned maintenance
Change the cartridge when the differential pressure indicator shows it is loaded, or at least once a year.

Frequently Asked Questions

Is this a genuine Festo part?

No. It is an aftermarket cartridge made to fit. It is not made by or affiliated with Festo; the Festo number 159594 and type LFP-D-MIDI-5M are shown only so you can match the part you are replacing.

How do I know it fits my filter?

Check the type plate on the filter housing. This cartridge fits LF-...-D-5M-MIDI filters and LFR-...-D-5M-MIDI filter regulators (5 µm grade). If your old cartridge is marked LFP-D-MIDI-5M or 159594, this is the replacement.

How often should it be changed?

Change it when the filter's differential pressure indicator shows it is loaded, or at the interval in your maintenance plan.

Do you ship to my country?

Yes, we ship worldwide. Shipping is calculated at checkout, and every order is covered by our 30 day money back guarantee and price beat guarantee.
