A unique endcap design which engages with the bowl, prevents vibration, improves stability and assists drainage. Colour coded elements make grade identification swift and simple.

Intelligent, unique, modular filter housing design

  • Filter elements are available in 25, 5, 1, 0.1 and 0.01 micron.
  • Pop up indicators are fitted as standard to some designs.
  • Differential pressure indicators are fitted to some designs.
  • Activated carbon filters must not operate in oil saturated conditions and will not remove certain types of gases including carbon monoxide and carbon dioxide.
  • Filter elements should be changed every 12 months or 8000 hours, whichever comes first.

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.

Donaldson Lube Filters and Hydraulic Filtration.

The Filter Guys

Spin-on Filters

Donaldson durable lube filters keep your equipment running at its best to let you focus on what’s most important, getting your job done.

Donaldson Endurance Plus Additive Replenishment Technology Filters

These filters are designed for today’s emissions compliant EGR engines, use a controlled chemical release process to replenish the additives in the engine oil and deliver extended drain intervals, often double that of standard filters. These filters are a direct replacement and require no system modifications or special maintenance.

Cartridge-style Filters

Donaldson offers a complete line of cartridge-style lube filters for all makes of equipment.

Continous Product Development

Donaldson has applied its patented radial sealing technology to spin-on style lube filters. The radial seal design provides a consistent, reliable seal, enhanced structural performance and optimum protection.

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.

Damaged or Missing Vac Valve.

The Filter Guys

The Vacuator™ Valve, a standard item on most Donaldson air cleaners, is an important part of the functionality of the air cleaner during the pre-cleaning stage.

If your Vac Valve is cracked, torn, missing or remains open, dust particles that are normally expelled can deposit themselves onto the filter and will significantly shorten the filter service life. It will need replacing.

For proper operation, the valve should be located at the lowest point on the air cleaner or with the dust cup pointing down. Normal engine pulsing and operation causes the Vacuator™ Valve to open and close. This action automatically expels any collected dust and water. The valve also releases its load when the engine is stopped.

Ever considered…. T.R.A.P. Breathers?

The Filter Guys

T.R.A.P. BREATHERS

(Thermally Reactive Advanced Protection)

Part No. P56 4669

 

The T.R.A.P. breather begins absorbing moisture at 15% relative humidity compared to 40% humidity for silica gel. This is particularly advantageous for use on short cycles of hydraulic circuits.

Increased prevention of condensation at an earlier stage helps prevent corrosion, maintain fluid quality and extends fluid life.

Its lightweight robust structure makes it is suitable for stationary and mobile applications and it’s also effective to -40F.

The reversible flow through the media allows moisture to exit the tank or reservoir.

It stops particles down to 3 micron.

1” NPT

A visual indicator, activated by pressure differential, flashes red to indicate change is needed.

Replacement and installation is easy. Simply hand tightens.

Call Sterling Filtration for more details.
