Filter elements for compressors.

The Filter Guys

Filter elements for compressors.

Pneumatic tools are ineffective if not maintained correctly. Dirt and liquid particles in your compressors air line can cause lengthy and expensive breakdowns or completely destroy your equipment. Regular maintenance is essential to avoid this happening especially at this time of year when cold temperatures can cause freezing of water droplets that may collect in your air lines.

Sterling Filtration Ltd can offer a wide range of filter elements to service your compressor machine needs. We have a wide range of parts available through our extensive supply chain to service machines including, but not limited to, Ingersoll Rand, Zander, Bauer, Hydrovane, Kaeser, Husky and Compair compressors.

We supply 1, 0.1 and 0.01 micron filter elements for inline compressed air use as well as being able to offer the complete assemblies too. We also stock air, oil and fuel filters for large compressor engines as well as air/oil separators for many applications.

Remember it is cost effective to regularly service your filter elements than not service your equipment. A strict maintenance procedure can stop a problem before it starts.

Compatibility of Filter Media with Hydraulic Fluids

The Filter Guys

Compatibility of Filter Media.

Filter media can be divided into two broad categories, natural fibres (usually cellulose) and synthetic or man made fibres (usually fibre glass or woven wire mesh), although many different variations and types of media do exist, many filters fall into one of these two categories.

Fluid to be Filtered Recommended Media
Petroleum-based Cellulose, Glass fibre
Phosphate Ester Glass Fibre
Diester Glass Fibre
Water Glycol Glass Fibre
Water-Oil Emulsion Glass Fibre
Biodegradable Fluid HWCF* Glass Fibre
Course Filtration Wire Mesh

* High water content filtration

Notes on seals:

Filters with seals made of BunaN are appropriate for most applications involving petroleum oil and some high water content fluids. Filters with seals made of Viton® of Fluorel® (both fluoroelastomers) are required when using diesters, phosphate ester fluids.

(Viton and Fluorel are registered trademarks of DuPont Dow Elastomers and 3M)

Don’t Throw Away a Good Filter Just Because it Might Look Dirty.

The Filter Guys

Don’t Throw Away a Good Filter Just Because it Might Look Dirty.

Although this air filter may look “dirty” – It can go plenty more miles. Installation of a restriction indicator can save you money and time.Why Service By Restriction?

Proper air cleaner servicing will result in maximum engine protection against the ravages of dust. Proper servicing can also save you time and money by increasing filter life and dust cleaning efficiency. By using proper filter restriction measurement tools you will use the full life of the filter at maximum efficiency. Don’t be fooled by filter appearance: it should look dirty.

The only way to determine when a filter is plugged or plugging is to measure the restriction on the system with the engine working at max airflow.

Two of the most common air cleaner servicing problems are:

1. Over-servicing: the least efficient time in the life of the filter is when it is new. Filter elements increase in efficiency as dust builds up on the media.

2. Improper servicing: your engine is highly vulnerable to abrasive dust contaminants during the servicing process when the filter is removed from the housing. A leading cause of engine damage is due to careless servicing procedures.

Watch Out for Old Compression Gaskets.

The Filter Guys

Watch Out for Old Compression Gaskets. When changing any filter that has a gasket – use caution as old gaskets may stick.

A compression seal is a means of preventing migration of liquids, gases or solid contaminates across a joint or opening in an assembly or housing. A seal not only prevents the escape of fluid from inside and foreign material from entering the system from outside, but it must provide for easy installation and removal. A new gasket is critical for proper filter function.

Remember…

  • Remove used gaskets and clean the sealing area thoroughly
  • Always use a new gasket with a replacement filter
  • Over-tightening the filter may damage the head
  • Dispose of used filters properly

Mann & Hummel Centrifuges/Oil Filters

The Filter Guys

MANN+HUMMEL centrifuges clean oil by generating centrifugal force 2,000 times greater than gravity. It is this force that separates solid contaminant from the oil. This technology has been proven to remove contaminant down to a sub-micron size, which is advantageous to both engine producers and users.

The Benefits:

• Cleaner oil

• Extension of oil life

• Lengthens service intervals

• Reduces engine wear

• Enhances long-term preventative maintenance

• Reduces maintenance costs

• Cuts waste disposal costs

• Reduces application down time

• Maximises in-service time for vehicle/engines/machine

MANN+HUMMEL centrifugal oil cleaners are internationally recognised in providing superior bypass filtration for the removal of contaminant from the lubricating oil of Diesel engines. The technology can also be successfully used for gearboxes, hydraulics and other industrial fluids.

MANN+HUMMEL provide its centrifuge technology to the following market sectors:

• Trucks

• Buses

• Marine

• Power Generation

• Mining Machinery

• Locomotives

• Construction

• Agriculture

• Military

• Industrial Fluids

• Reduces total cost of ownership

• Helps ensure clean combustion and fuel efficiency

• Supports engine technology for the reduction of exhaust emissions (e.g. exhaust gas recirculation)

• Fast return on investment

Full flow filters are designed to process all the oil used to lubricate the moving parts of the engine. However, the need to maintain a high flow and limit pressure drop across the filtration media restricts the ability to filter out sub-micron particles. This job is taken over by the centrifugal oil cleaner in the bypass. The MANN+HUMMEL centrifugal oil cleaner processes approximately 10 % of the oil flow provided by the engine pump before returning it directly to the engine sump. The removal of particles by centrifugal force is based on their relative density and therefore there is no restriction on contaminant size.

Micron Rating. What are they and why is it important?

The Filter Guys

What is a Micron?

A micron is a measurement of size. It is one millionth of a metre (1/1000000m) or a thousandth of a millimetre (1/1000mm). In filtration, a micron rating is a rating of the media’s capacity to stop dirt (it is not an efficiency rating). The micron rating will be nominal or absolute.

A nominal micron rating means that a media may be explained as 10 micron but that is a mean average, it probably varies between 5 and 15 micron over the surface of the media itself; this often applies to cellulose media which is a natural product. Engine oil and fuel filters are often nominally rated.

An absolute micron rating means that the media has a uniformed surface and will ‘do what it says on the tin.’ A 10 micron absolute filter will not allow particles of 10.1 micron or bigger through at all. Absolute filters are man made products, such as glass fibre, and are manufactured to an extremely high specification. Hydraulic filters are often absolute rated (but not necessarily for all hydraulic applications).

Why is it important?

In filtration the micron rating of the element is very important to guarantee its correct operation. The wrong type of media can mean more dirt gets through the filter than you want and this can cause wear and tear and even complete breakdowns of your engines and hydraulic equipment.

Take a lubrication system on your engine. Oil is pumped between the moving parts of the engine, this oil contains particles, if the oil isn’t filtered before being sent into the engine then wear and tear will occur. The space between moving parts may only be 30 or 40 microns. If oil contains particles of that size then dirt is going to jam and consequently build up between moving parts. Over many hours (or years) of operation with inadequate filtration this build up of dirt will cause the moving parts to jam which will cause catastrophic failure of an engine leading to expensive downtime and repair costs.

Of course, over time filters will clog with dirt too but they are easily sourced from Sterling Filtration Ltd and replaced. They hold the damaging particles so the engine doesn’t have to. A filter may cost ten, twenty, fifty, one hundred pounds and sometimes even more, but compared to the cost of downtime of a machine and the stripping and rebuilding of an engine they are easily the most cost effective way of keeping your engines and machinery running properly all of the time. See your operators manual for service intervals.
