NFMP-A Series (30-250 CFM)
Mid Pressure Filtration
The Next NMPF mid pressure range filter series is tested in accordance with ISO 8573-1 standards. The NMPF-A filters have (2) ranges of efficiencies at 580 psig. for removing contaminants as small as 0.01 microns, with connections from– ½” to 1” npt sizes. A stainless manual valve drain is standard for optimal and reliable removal of liquid contaminants. It’s 2-part permeant pressure cast molded aluminum housing that goes through the process of chromo phosphate in addition to being externally powder coated. Low pressure drop is achieved through optimal flow path design. The high efficiency bowl and non-turbulent lower filter zone assure that no condensate gets re-entrained in the air stream. The NFMPs’ seal cannot be opened while the filter is under pressure, offering additional efficiency. The stop lock feature design allows for easy disassembly and element changeout but also prevents over tightening of the filter body.
NEXT offers filtration products in an application range from general purpose air to the most stringent food and pharmaceutical applications. Next’s NFMP filters are available from 35 to 250 cfm, @ 580 psig, with design temperatures of 35 °F (2°C) to 176 °F (80°C)

Filter Media Designed for Compressed Air
High quality compressed air filtration starts with selecting the correct filter media. Next uses superior-quality filter media with a new hybrid technology. Our elements stop the perpetual discussion about the use of filter media with or without binders because they are layered with body types, tailored to the filtration task. This neutralizes the inherent disadvantages and, as a result, retains the advantages of both types. The fine filter media is protected on both sides using a supporting fabric to increase both the stability and reliability.
Pleated Filter Elements
Pleated filter elements provide significantly greater filtration area than non-pleated. The higher filter area provides more void space for holding contaminants which reduces the differential pressure caused by retention of solid particles. The service life of the filter element increases proportionally which results in operating and maintenance cost savings.
Incorporated Drainage Media
The filter and drainage media are supported between two stainless steel supporting cylinders, eliminating any potential detachment of the filter media. The drainage media is located inside the filter element, eliminating potential handling damage. The stainless-steel cylinders have big, diamond-shaped openings for optimum flow conditions. Compared to punch-hole versions, their contribution to differential pressure is much lower and they are much more environmentally friendly because they are made from expanded sheet metal, i.e. without metal scrap.
Two-stage dry type Separation
During dry-type separation without-to-inside flow through the filter elements, the drainage media functions as a pre-filter stage, preventing coarse contaminants from entering the fine filter media. As a result, the differential pressure caused by contaminants is reduced and the service life of the filter is extended. As an additional advantage, the filter elements can also be used for wet type filtration.
NFMP-A Optional Features
The Next condensate drain series, drains without the loss of compressed air and guarantees a secure and economical drainage of condensate for any application.
The sizing of the condensate drains matches perfectly the volume flows and guarantees secure drainage even with higher condensate volumes.

Principle of Operation
- Contaminants are introduced at various stages of the air compression cycle. Removing these contaminants is vital to help ensure part quality, avoid machine damage and protect the air stream.
- Compressed air enters the filter housing inlet. The inlet design helps optimize airflow as compressed air moves into the physical medium of a filter element.
- Then, Untreated compressed air passes through filter material designed for retention of particles such as liquid oil, oil aerosols, dirt and scale.
- Finally, the treated, clean compressed air flows down stream to other inline components or point of use.
- Removed condensate moves from the treated air to be easily drained.

Next Air & Gas Performance Advantages
Compact & Light Weight
Advanced housing and element design prove a smaller, more compact and light weight filter which is efficient and easy to maintain.
Tie Rod Design
The NFMP Filters employ an internal tie-rod to mount MFMP-E elements in the filter. This style allows for easy post mounting of the elements.
Filter Connections
More port sizes are available to match both pipe size and system flow rate, giving additional customer choice. (1/2” to 1” npt.)
Fully Corrosive Protection
The NFMP aluminum body goes through a chrono phosphate process and also powder coated with an epoxy finish for full corrosion protection.
Stainless Steel Manual Drain
Specially designed stainless-steel auto manual drain protects from corrosion and other contaminants.
Deep Bed Pleating
For particle and aerosol removal, deep bed pleating provides 450% more filter media than an ordinary element, giving a larger filtration area, lower flow velocities, increased dirt holding capacity, lower running costs and a more compact filter element. Graded density further improves filter life and overall performance..
