With more than 45 years of filtration experience, Swift Filters understands the technology, the issues and the requirements of producing reliable cost-effective filtration solutions. Contamination is the dominant factor in the failure of hydraulic and lubrication systems. Contamination affects component wear and downtime, and ultimately the costs of operating your fluid pressure system. With proper filtration, fluid cleanliness is improved resulting in longer fluid life, less maintenance time is required, equipment is more reliable, costly component replacement costs are reduced and there is less downtime.
We excel at designing and manufacturing both standard and custom filter elements. Our products are used in the most demanding applications, including military, aerospace, high performance racing and a number of heavy duty industrial markets, just to name a few.
All Swift Filter elements conform to the latest ISO standards. There are a number of ISO quality standards that are applicable to filtration, including:
Bx(c)=1000 (ISO 16889) | 2.5 | 5 | 7 | 12 | 22 |
Bx=200 (ISO 4572) | ‹1 | 3 | 6 | 12 | 25 |
There are a number of ISO target cleanliness codes that can be used to help when designing your system. Conditions that include cold starting, high levels of shock and vibration, if the component can affect safety and/or reliability, or any other severe operating conditions or combination of conditions should be part of your design criteria when selecting the proper filters.
Component | ISO code |
---|---|
Servovalves | 16/14/11 |
Proportional valves | 17/15/12 |
Vane and piston pumps and motors | 18/16/13 |
Directional and pressure control valves | 18/16/13 |
Flow control valves and cylinders | 20/18/15 |
New unused fluid | 20/18/15 |
The NFPA (National Fluid Power Association) also publishes several standards applicable to filtration elements which are available on their website.
The typical filter element choices are Cellulose, Micro-Fiberglass and synthetic materials and Stainless Steel Wire Cloth. Each media has its own level of performance, with varying levels of cost, capture efficiency, dirt holding capacity, differential pressure capability and system life. See our Comparison of Filter Medias to learn more. When making a choice for your application contact our customer service department should you need any help. For example, in low pressure applications cellulose elements may be appropriate, while high pressure corrosive applications may call for stainless steel wire cloth elements. For the highest level of Capture Efficiency and Dirt Holding Capacity micro-fiberglass filters are an excellent choice. When choosing filter element media, lifecycle costs are an important consideration. The ability to clean and re-use stainless steel mesh elements, or the high efficiency of micro-fiberglass has an effect on longer term cost considerations. Let us assist with any application questions or problems.
