This element overview is designed to provide a brief snap shot of all our filter elements.
Coalescing
Our coalescing filter elements are completely disposable, made entirely from borosilicate glass microfiber. The coalescing elements have a two-layer structure, an inner particle capture-layer and an outer drainage layer. Liquid droplets remain mobile once captured, and travel through the fine-pored capture-layer, along the intersecting microfibers, growing in size as they progress. These coalesced droplets are transferred to the large-pored drainage layer from where they drain by gravity into the filter bowl. Coalescing elements should always flow from the inside to the outside of the element so that proper draining of liquids can occur. These elements will simultaneously collect liquids and particulates.
C Grade – Coalescing (Oil and Water Removal)
Elements are specifically designed for the removal of liquid aerosols and particulate from gases in both corrosive and non-corrosive applications. The C type element is constructed of two layers of borosilicate microfiber.

The elements consist of five layers of precision-woven 316L stainless steel mesh formed into cylinders and sintered together.
Technical Information
- Material of Construction: Five Layer 316L Stainless Steel with PTFE or Viton End Seals (Pictured with PTFE)
- Type of Application: Sample Conditioning, Fast Loop, Steam, and Liquid
- Maximum Temperature: 400ºF
- Appearance: 316L Stainless Steel
- Flow Direction: Both
- Micron Sizes: 01, 03, 10, 25, 50, 100, and 200
We offer seven standard grades of filtration, which fit our Headline Filters line of housings, as well as other proprietary brands. Micron Sizes: 0.5, 1, 3, 10, 25, 50,100, 200. Grade 25 (25 micron) is widely used to protect pumps and valves while grade 03 (3 micron) is recommended for removal of pipe scale from steam. The SS Elements are environmentally friendly because they are durable and non-absorbent, they can be backwashed, cleaned and reused, thus eliminating a major disposal headache.
Stainless Steel Single Layer Screen
Ideal in liquid applications where particulate removal is needed. Used across a wide variety of applications these low cost filters are the perfect solution as prefilters or in corrosive heavily contaminated streams.
Technical Information
- Material of Construction: Single Layer 304 Stainless Steel
- Type of Application: Pre-Filter for Particulate, Diffuser in Liquid Service
- Maximum Temperature: 400ºF
- Appearance: 304 Stainless Steel
- Flow Direction: Outside to Inside
- Micron Sizes: 10, 25, 50, 75, 100, 200, and 500 (other sizes available upon request)
The LSS is a single layer precision woven screen that offers moderate filtration efficiency. Because of the small diameter and short length, these elements do not require a support core.
For Capillary Well Service our 50 and 100-micron SS filter screens offer exceptional filtration while still providing high flow rates for such a compact design. The element’s small diameter eliminates the need for a collapse core thus increasing true filtration area and providing longer element life.
PTFE – Corrosive Service
PTFE filter elements are recommended for liquid filtration where our microfiber and stainless steel elements are unsuitable. Made from pure PTFE sintered (under pressure) into cylinders. The “PT” elements have outstanding chemical compatibility and extreme hydrophobic characteristics, which make them ideal for liquid sampling applications.
No end caps or gasket materials are required for a positive seal.
Typically Used with Our PTFE & Kynar Housings.
Technical Information
- Material of Construction: PTFE
- Type of Application: Particulate Filtration in Corrosive Service
- Maximum Temperature: 400ºF
- Appearance: Pure White
- Flow Direction: Typically Outside to Inside
- Micron Sizes: 03, 25
PTFE Elements are typically used to eliminate particulates, but also can remove small amounts of liquids, because of their pore structure, and hydrophobic characteristics.
Sintered Polyethylene (PEL) – Particle Removal in Liquid
Slight pressure will force liquid through the element while at the same time repelling any dirt “particulate” which is encapsulated in the water. The element uses two filtration techniques, surface area and depth. Typical flow direction is out to in, since dirt is visible on the outside surface area and the outer diameter is larger for increased surface filtration. The elements may be back flushed in place, or cleaned ultrasonically, however their low cost makes it economical to dispose of.
Technical Information
- Material of Construction: Virgin Polyethylene
- Type of Application: Particle Filtration in Liquid
- Maximum Temperature: 212ºF
- Appearance: Bright White
- Flow Direction: Either Direction
- Micron Sizes: 10, 25, 75, & 100
PEL filter elements are constructed from virgin polyethylene (H.D.P.E.). The material is in powdered/granular form and then compressed into a sintered tube. This process allows the filter element to be free from foreign binders. Thus, the only compatibility issue is with polyethylene. No end caps or gaskets are necessary to seal the element into place. Axial compression is used to create a seal on the flat surface of the element. The PEL elements are naturally hydrophobic.
Pleated MicroGlass – Liquid Applications
These elements are specifically designed to be used in our 150/160 high pressure filter housings where high flow rates and high efficiency filtration is required. The inner spiral wound 304 Stainless Steel support core and reinforced pleats provide high flows along with added durability.
Technical Information

- Type of Application: Remove Particles from Liquid Stream
- Maximum Temperature: 140ºF
- Appearance: Perforated Metal with Black End Caps
- Flow Direction: Outside to Inside
- Micron Sizes: 03, 10, & 25
Micron Sizes Available: 03, 10 & 25
Membrane Separators
The ultimate filter for removing liquids is a PTFE based membrane. These membranes allow gases to pass while blocking larger liquid molecules. We offer a comprehensive line of membrane separator holders that are used to protect analyzers. We recommend that a coalescing filter be installed upstream of a membrane to protect it from particulates and flooding.
Guardian Membrane Filters
For absolute liquid removal in extremely low flow applications we recommend our Guardian Membrane Separators. These units are designed for critical point-of-use service. The actual membrane is a flat disc that is sandwiched between two plates. The gas flow permeates the membrane while liquid is blocked and runs off into a drain. Our membranes are interchangeable with other proprietary brands.
Technical Information
- Material of Construction: PTFE Membrane
- Type of Application: Analyzer Protection
- Maximum Temperature: 300ºF
- Appearance: White Disc
- Maximum Flow Rate: 18 LPM
- Micron Sizes: M1HG – 0.1 Absolute (Low Flow); M2HG – 0.8 Absolute (High Flow)
PTFE Membranes are solely utilized in our GMS Series of Filters. We do not offer sizes to fit our complete filter housing range. Maximum flow rate on our largest membrane is 18 LPM.
Guardian Membrane Environmental Filters
We also offer a full range of point-of-use disc and syringe filters for environmental, analytical, lab, and medical markets. We stock a full range of options for the most common applications. The GME series of membranes provide complete filtration for ultra-critical low flow sample conditioning.

Steam Elements
We offer two basic types of Steam Elements; Disposable Coalescing Borosilicate Microfiber and Five-Layered Stainless Steel elements for particulate and bulk liquid removal. Both types of elements are available in sizes to fit OEM steam sterilizer filter systems. It is important to have a condensate drain to immediately evacuate any collective liquids.
Disposable Steam Elements – Grade ZZ
Our 37/59-460-70ZZ OEM retro-fit steam elements are constructed of 100% borosilicate glass microfiber providing up to 95% efficiency against 0.01 microns. We utilize a PVDF binder which allows the element to function at temperatures up to 300°F (150°C). It is important to note that the 70ZZ elements should be changed-out every six weeks, and that solid particles will shorten their service life by reducing surface area which is needed to remove liquid droplets. A condensate drain is a mandatory accessory on a steam filter, ensuring immediate liquid removal. Every application is unique and must be monitored to ensure proper change out frequency. The particles will also increase the pressure drop, which can lead to element rupture. For added security, the element can be caged with inner and outer stainless steel support cores designated by a suffix of “X3”.
Technical Information
- Materials of Construction: Borosilicate Microfiber Glass with PVDF Resin Binder
- Type of Application: Sterile Air Applications

Five-Layer Stainless Steel for Steam Filtration
Stainless Steel elements are ideal for removing particulate from steam and can be used as a bulk liquid knockout. The elements’ five layers act as a coarse “coalescing” filter. We recommend the 3 micron as a good starting point for steam filtration and our SS-51-460-03T element retro fits into OEM housings.
Technical Information
- Material of Construction: Five Layer 316L Stainless Steel with PTFE
- Type of Application: Steam
- Maximum Temperture: 400ºF
- Appearance: 316L Stainless Steel
- Flow Direction: Both
- Micron Sizes: 01, 03, 10, 25, 50, 100, and 200
The 3 micron is recommended for removal of pipe scale from steam. The SS Elements are environmentally friendly because they are durable and non-absorbent, they can be backwashed, cleaned and reused, thus eliminating a major disposal headache.
L Grade – Sterile Air
These elements are bonded with a hydrophobic binder making them ideal for use where steam sterilization is required. The silicone binder prevents the pores from being filled with condensate, which can encourage bacterial growth. Maximum recommended steam pressure is 60 PSIG.
Technical Information
- Binder Type: Borosilicate Glass Microfiber with Silicone Resin
- Type of Application: Sterile Air Applications
- Maximum Temperature: 300ºF
- Appearance: White in Color
- Flow Direction: Outside to Inside
Efficiency at 0.01 microns. Suffix Grade designation:
