Draper Tools are available through us.

The Filter Guys

People often are unaware of the additional goods and services that we can offer. As a filtration company people don’t realise we offer extra services such as Draper Tools.

So with the weather on the up maybe it’s time to look at those garden improvements that you’ve been dreaming about all winter and spring. Shovels, rakes, lawn edgers, hoes, leaf collectors and everything else you may need to get your green fingers working are available through us.

Draper weed matting is an affordable and simple way to keep away unwanted growth so that the plants you want to grow can thrive.

Draper loppers and hand trimmers are a must to help you maintain those out of control overgrown bushes, so go on give your bush a trim this summer.

And for later in the year you’ll need a Draper leaf blower to help you clear away the autumn blues.

And when you’ve finished working hard you’ll need to put your feet up with a burger and a beer; but at the end of the summer don’t forget to get a Draper barbecue cover to keep things in tip top condition so you can do it all again next year.

How Filter Media Functions In a Filtration System

The Filter Guys

How Filter Media Functions. The job of the media is to capture particles and allow the fluid to flow through. For fluid to pass through, the media must have holes or channels to direct the fluid flow and allow it to pass. That’s why filter media is a porous mat of fibers that alters the fluid flow stream by causing fluid to twist, turn and accelerate during passage.

The fluid changes direction as it comes into contact with the media fibers, as illustrated above. As the fluid flows through the media, it changes direction continuously as it works its way through the maze of media fibers. As it works its way through the depths of the layers of fibers, the fluid becomes cleaner and cleaner. Generally, the thicker the media, the greater the dirt-holding capacity it has.

Looking at a cross-section view of the fibers:

we can see how the flow stream is accelerated as it flows into the spaces between the fibers.

This is applies to all liquid filters, be they oil, fuel, water of water glycol. For more information on filtration products and replacement elements please contact us for a chat. We’re here to help.

How Filter Media Collects Particles

The Filter Guys

How Filter Media Collects Particles. There are four basic ways media captures particles.

The first, called inertia, works on large, heavy particles suspended in the flow stream. These particles are heavier than the fluid surrounding them. As the fluid changes direction to enter the fiber space, the particle continues in a straight line and collides with the media fibers where it is trapped and held.

The second way media can capture particles is by diffusion. Diffusion works on the smallest particles. Small particles are not held in place by the viscous fluid and diffuse within the flow stream. As the particles traverse the flow stream, they collide with the fiber and are collected.

The third method of particle entrapment is call interception. Direct interception works on particles in the mid-range size that are not quite large enough to have inertia and not small enough to diffuse within the flow stream. These mid-sized particles follow the flow stream as it bends through the fiber spaces. Particles are intercepted or captured when they touch a fiber.

The fourth method of capture is called sieving and is the most common mechanism in hydraulic filtration. As shown at right, this is when the particle is too large to fit between the fiber spaces.

Vacuum Pump Filters

The Filter Guys

Air filters are an important part of any vacuum pump filters system. They prevent dirt from being sucked into the vacuum pump, and help avoid unnecessary wear. They offer minimum pressure losses and guarantee energy efficiency and long service life and can ensure your vacuum pump continues to operate at optimum performance levels.

The airtight vacuum air cleaners available at Sterling Filtration Ltd are designed for installation in air and gas pipes. They are airtight up to 1000 mbar negative pressure and equipped with a filter element. They are also used as intake filters in vacuum pumps.

Complete vacuum housings and replacement elements are available at Sterling Filtration Ltd. Tel: 01902 491118.

Mann Filter Air Dryers.

The Filter Guys

Brakes are amongst the most important components of a vehicle. Pneumatic braking systems on trucks and buses must be protected from corrosion to ensure efficient operation. To achieve this, a dry, clean pneumatic operating system is critically important. The MANN-FILTER air dryer cartridge provides the optimum solution by guaranteeing the best possible protection for braking systems. Advantages of the MANN-FILTER air dryer cartridge:

  • Highest possible resistance to pressure and pulsation
  • Strength and rigidity to counteract vibration
  • Premium quality desiccant provides optimum air drying performance
  • Efficient oil and water separation and retention
  • Integrity of sealing materials assured
  • Superior corrosion protection

Air dryer cartridges with an integrated coalescence filter retain particles, dry the air in the compressed-air brake system and most effectively separate fine oil droplets. The coalescence effect combines oil droplets (aerosols) which can damage the system components into larger droplets, thus ensuring reliable system protection. MANN-FILTER air dryer cartridges contain an extremely high quality drying agent demonstrating high water resistance and mechanical stability.

Benefits:

  • As well as the benefits of the standard version, the air dryer cartridge with integrated coalescence filter also provides:
  • improved protection for the compressed air and brake system of commercial vehicles
  • longer service life of the system components, for example pressure regulating equipment and seals
  • lower service costs and shorter downtime
  • easy to retrofit to replace standard air dryer cartridges

The MANN-FILTER range of air brake dryers is available at Sterling Filtration Ltd.

Changes to Gas Oil Used in Off-Road Equipment.

The Filter Guys

From the 1st of January 2011 all gas oil (red diesel) for use in off road machinery and boats will contain no more than 10mgs of sulphur per kilo of fuel (current level is 1000mgs/kg). The changes are to reduce burned sulphur from entering the atmosphere. The Department of Transport are advising all gas oil users of the following precautions when storing and using red diesel for off road and recreational boat use:

Increased care when storing: The oxidation stability of this fuel will be poorer than that of current gas oil. This can cause solids to form in the gas oil. This will cause increased contamination that will require filtering from the gas oil. Suitable and regular filtration of the fuel will help prevent wear and tear on transfer pumps or off road engines.

Water removal: Water in fuel encourages bacterial growth which can block fuel systems and damage engines. Increased use of bio fuel as an additive to modern gas oils means that there is an increased risk of bacterial growth where water is present. Ensuring that suitable water separators are fitted can help reduce bacterial growth and reduce down time from breakdowns.

Solvent characteristic of the low sulphur fuel: The new sulphur free gas oil has a more solvent characteristic than current gas oil and will potentially remove any deposits within the storage tank. It is advised that fuel tanks are cleaned and equipment filters be replaced after the initial 2-3 tank fills of sulphur free gas oil and then be maintained and serviced regularly. If ever in doubt, change your fuel tank filters.

The cost of regular filter servicing is much lower and cost effective than the cost of even one single pump or engine fuel system replacement.
