Orange-Peel Melt Blown Filter Cartridge, PLM Series
The Pullner PLM orange-peel melt blown filter cartridge is a melt blown cartridge with orange texture: a dimpled outer surface that adds mechanical strength and rigidity under elevated differential pressure. It is used for pre-filtration of high-viscosity industrial process liquids. The media is 100% polypropylene (PP), rated 1, 3, 5, 10, 20, 30 or 60 µm, on a 63 mm outer diameter in 5″ to 40″ lengths. Maximum differential pressure is 4 bar at 21°C and the temperature limit is 80°C. Send your current model or duty for a fit check and quote.

The orange-peel melt blown cartridge uses a textured, dimpled outer surface for enhanced mechanical strength and pressure resistance. Its dimpled profile provides additional structural rigidity under elevated differential pressure, which suits high-viscosity liquids and duty where the pressure across the element runs high within its rating.
The problem it addresses is deformation. A depth cartridge pushed by a thick fluid or a steep pressure drop can compress, and a compressed depth structure no longer holds its grade. The orange-peel texture stiffens the outer face without changing the media: 100% polypropylene, graded 1, 3, 5, 10, 20, 30 or 60 µm, on a 63 mm outer diameter in 5", 10", 20", 30" and 40" lengths.
End caps are DOE or SOE (226 fin, 226 flat, 222 fin, 222 flat), with silicone, NBR, Viton or EPDM seals. Rated limits are 4 bar at 21°C and 2.4 bar at 80°C. The orange-peel cartridge shares the PLM specification with the groove type, used on high-solids feeds, and the mini-grooved surface, used for finer polishing.

Recommended Pullner product family
Melt blown filter cartridges, PLM series. The orange-peel surface suits viscous or higher-pressure duty; the groove type and mini-grooved surfaces share the same specification for other duties.

- Validation requirement
Can the PLM orange-peel cartridge replace the melt blown cartridge we run now?
It is a replacement option where your housing takes a 63 mm OD cartridge in 5" to 40" lengths with DOE or SOE end caps. Send the current model, end cap and seal type. Engineering confirms dimensional fit first; performance on your fluid is confirmed by a sample or trial.
How is it validated before switching?
Start with a fit check against your housing, then run a sample on the actual feed. Compare differential pressure rise, change-out interval and downstream quality against the cartridge in service. Scale the order only after your team accepts the trial result.
What data or documentation is available?
This page publishes the micron grades, media, dimensions, end caps, seals, flow, pressure and temperature limits. Pullner manufactures under ISO 9001. Ask engineering which inspection or test records can accompany your order before you request a sample.
What are the operating limits?
Maximum temperature is 80°C. Maximum differential pressure is 4 bar at 21°C, falling to 2.4 bar at 80°C. The media is polypropylene, so confirm chemical compatibility for your specific fluid, concentration and temperature. The cartridge is rated for liquid service.
What is a melt blown cartridge with orange texture?
It is a melt blown polypropylene cartridge with a dimpled, orange-peel outer surface. The texture adds mechanical strength and rigidity under differential pressure without changing the media. Pullner's PLM orange-peel cartridge is rated 1 to 60 µm on a 63 mm OD, up to 80°C.
