Merry Christmas and a Happy New Year to all.

The Filter Guys

2011 has again been a tough year for many with no real end yet in sight to the tough economic conditions that have blighted the country. But we’re still here, soldiering on as we all have to do and we’ve made it to another Christmas time. The trees are up, the presents are wrapped and the mince pies are eaten! It’s a time for family and friends not business, let’s forget about work, let the hair down and relax because in January we’ve all got plenty of hard work to be getting on with.

So from everyone at Sterling Filtration Ltd, “Merry Christmas and a Happy New Year to all of our customers and suppliers.”

Let’s make 2012 a good year.

Don’t get into a spin over your element life; get into Top-Spin pre-cleaners.

The Filter Guys

Similar to the pre-cleaners in our previous article, the Donaldson Top-Spin pre-cleaner will extend your main element life, boost system efficiency and extend engine life. It separates up to 85% of incoming contaminant as per ISO 5011/SAEJ726, it extends air filter life therefore reducing operating costs and removes 99% of particles of 20 micron or larger before they can reach your engines air intake system.

A full range of Donaldson Top-Spin pre-cleaners are available from Sterling Filtration Ltd.

Ever considered using a pre-cleaner on your air intake system?

The Filter Guys

Have you ever considered a pre-cleaner on your air intake system? Easily installed and maintained, these products can increase the life of your main air element significantly, which over time can help to reduce your maintenance costs.

A full view pre-cleaner separates up to 75% of incoming dust before it enters the engine air intake system. It has a durable, lightweight, non-corrosive construction and comes with mounting clamp to fit. The clear full-view plastic bowl lets the operator easily see when servicing is required.

The Importance of Diesel Filtration.

The Filter Guys

Diesel is the most commonly used fuel in heavy duty applications and requires filtering to ensure that any contaminants have been removed before they can cause stoppages, or serious damage resulting in complete failure, to the diesel system components.

In-line fuel elements can stop the larger, damaging contaminants such as rust and sediment from the fuel tank entering the fuel system. Diesel filters are important as they have to protect the fuel pump and injectors not only from abrasive particles but also from minute droplets of water often found in diesel fuel.

Injectors and diesel pumps are precision machined components and are very costly to repair or replace. It is much more cost effective to change the filters at their regular service intervals rather than have to pay the cost of even one breakdown repair bill.

Sterling Filtration Ltd stocks a wide range of diesel fuel filter canisters and elements for all types of application, as well as water separating filters and fuel additives, that will keep your fuel clean and your engine running and maintain your diesel filtration.

Hydraulic Oil Testing.

The Filter Guys

The testing of hydraulic oil to measure its contamination level can be a beneficial task. A large number of hydraulic circuit failures and breakdowns can be attributed to poor filtration methods and oil contamination. By measuring the level of contamination you can make sure that the level of filtration that you are using is adequate for your needs and if not what needs readjusting to correct your problem.

Sterling Filtration Ltd can offer you a complete service, taking your sample and sending it for laboratory analysis, and compiling a complete report of the cleanliness level of your hydraulic oil. We can also offer you any improved filtration solutions should you require them.

The lead time on this service is usually 4-5 working days following receipt of the sample to you receiving your analysis report.

Air Filter Efficiency

The Filter Guys

Whether your air filter is fitted to a car, a truck, a tractor or a digger air filter efficiency will be measured in the same manner.

Older equipment might have used an oil-bath air cleaner but today it is almost entirely dry-type air filters that are used. They are more efficient and easier to service. They generally use treated cellulose media, pleated to give as much surface area as possible within the filter container. The more media is used the greater the air-flow that the filter can handle and the longer the service life before cleaning or element change.

As little as 100 gm of dirt passing into a diesel or petrol engine can “dust” it to the degree where it needs to be reconditioned. A dry-type air filter, from any of the major reputable manufacturers, will have an efficiency in excess of 99.9%. In other words for every 100 gm of dirt hitting the air cleaner element less than 0.1 gm will pass through and into the engine.

But how is its efficiency measured?

Under laboratory conditions special test dust, typically a carefully defined mix of different particle sizes, often from the Arizona desert, is mixed with the air flow entering the air cleaner assembly. Any dust that passes through will be caught on a massive absolute filter which would first have been weighed. After the test period the absolute filter is weighed again. This weight difference is then compared with the difference in weight of the air filter element itself before and after the test. The efficiency is a simple calculation and is expressed as a percentage.

The most commonly used test dust is defined as coarse and has the following particle size distribution by weight;

Size in microns Percentage
0 –5 12 +/- 2
5 – 10 12 +/- 3
10 – 20 14 +/- 3
20 – 40 23 +/- 3
40 – 80 30 +/- 3
80 – 200 9 +/- 3

Before deciding on which air cleaner to use always check what its efficiency is – for the sake of your repair bills at least!

Bespoke, made for the job filtration.

The Filter Guys

There are fewer things more annoying than trying to start the engine on your machine or vehicle only to find the fuel filter is blocked, but one of those more annoying things is turning up at the trade counter of your spares supplier only for them to tell you that it’s so rarely used they no longer stock the filter or it’s become obsolete altogether. This isn’t just an issue with fuel filters. Air, lube and hydraulic filters all become yesterday’s technology eventually. But with the economic conditions and tight company budgets that are currently restricting business growth you might not want to spend money on buying a completely new machine with filters that are accessible.

Here at Sterling Filtration Ltd we can sympathise with this situation. That is why we offer to the market a bespoke filter manufacture. Turning out small to medium sized, bespoke product runs we can offer you a solution that’s affordable and obtainable. So don’t bang your head against the wall next time someone tells you your filter requirements are impossible to fulfil, call Sterling Filtration and we’ll take care of everything.

Shortcuts lead to clean up downtime.

The Filter Guys

We recently visited a large site of one of the leading scrap metal processing companies in the UK and were surprised to find the hydraulic oil tank of their primary baler “open to the atmosphere”.

From new it had been fitted with a series of three Filler Breathers one on each of the 76mm diameter tank top filler pipes. They had been initially removed because “It makes it quicker to top up the oil level” and never replaced.

We had been called to site to investigate short life on the expensive Pall hydraulic filter elements used in the baler circuit.

The results of an oil analysis showed a high level of 5 to 25 micron dust particles and a lot of free and emulsified water. The dust particles were “blinding” the filter element explaining the short service life. The emulsified hydraulic oil would result in accelerated wear of the pumps and motors in the baler circuit.

The operators had not appreciated the effects of their actions, that what seemed like a short cut would actually cause expense and cost more downtime.

All too often we witness similar cases where people underestimate the importance of quality well maintained filters and subsequently find machines and equipment being forced off line.

To rectify the problem the company had to hire a mobile off-line filter system with a water absorbing hydraulic cartridge and a separate 5 micron hydraulic element to clean up the system.

The elements in the breathers have been renewed and the breathers refitted. This small investment will be repaid many times over through the extended life of the hydraulic oil, the reduced frequency of hydraulic filter changes and the longer service life of the pumps and motors
