Quality 

The GUD Filters quality system is regularly assessed by the South African Bureau of Standards to TS 16949: 2002. Our quality system, products and processes are audited regularly by OEMs to ensure their specific requirements are met and to this end, we have achieved the coveted Ford Q1 Status.

Our dedication to quality and customer satisfaction cultivates a team ethic that extends throughout the company, and includes suppliers of raw materials and services. A supplier development program encompassing quality, productivity and costing issues is vigorously pursued.

The effectiveness of the entire GUD quality system and its quality ethic has been a cornerstone of the company since its inception; thereby ensuring products consistently perform to the highest standards.
 


Diesel Fuel Filters (Multiport)

GUD celebrated one of the most exciting manufacturing developments in the company's history, with the opening of our diesel filter line. The line boasts technology and performance standards unparalleled anywhere in the industry.

The line operates in a clean room environment comparable to the operating room of a hospital. Diesel filters operate under extremely high pressures, and as a result, there is a huge danger of dirt damaging the injectors. For that reason, the clean room was designed to minimise the build-up of dirt in the actual manufacturing process, almost completely eradicating any impurities up until the time of the filter being installed in the vehicle.

With all doors air-locked, all joints fully sealed, and air conditioning entering through eight dual filter packs to create an over-pressured enclosure, the manufacturing environment is impeccably clean, comfortable, and secure from outside contamination. In addition to this, employees operating on the line do so wearing specially designed lint-free suits.

The focus on hygiene is continued throughout the packaging and inspection process, to ensure that no dirt can accumulate along the way. All components are cleaned internally and stored in appropriate containers and racks. Furthermore, received goods are suitably protected to ensure the continuation of the cleanline standards.

The smaller size of diesel engines, as well as the higher speed at which they function, creates a need for decreased tolerances and therefore maximum efficiency in order to ensure Extended Service Intervals. GUD products are guaranteed to meet and exceed the efficiency needs of a modern diesel engine. These filters feature highly complex piping (hence the name, multiport), which serves to perform the following functions:

1.    Inlet from tank.
2.    Outlet to engine.
3.    Excess fuel back to sump.
4.    Hot fuel back from injectors to warm the diesel to prevent the wax in diesel solidifying at colder temperatures.
5.    A water extractor point. If there is no pre-filter, water will be removed by the multi-layer media and have to be sucked out by a special device.
Rigorous testing and research went into the design of the room and equipment, and it serves as testimony to GUD’s unwavering commitment to going beyond market expectations to provide customers with the highest quality products possible. GUD’s sterile manufacturing room and rigid controls give us a distinct competitive advantage as we strive to go the extra mile to ensure your car’s engine can do the same.
GUD vs. Competitor
The purpose of a filter in your engine is to KEEP OUT HARMFUL CONTAMINANTS, carried by the engine’s air, oil and fuel supplies.

Contaminants can be in the form of dust, sand, soot, water and engine wearing metals. If these contaminants are NOT filtered out, rapid engine wear will occur or worse, COMPLETE ENGINE FAILURE.

A sub-standard filter WILL result in premature wear. On the face of it and to the untrained eye, sub-standard filters often don't look bad from the outside and are therefore deemed to be good quality. This is where the unsuspecting are led astray. Filtration performance far outweighs physical appearance.

To ensure you fit the best quality filter to your vehicle, follow these simple rules and be assured of Great Engine Protection and maximum engine life:
 
1. Always buy a reputable and trusted brand, such as a GUD Filter.
2. Always look for a comprehensive product warranty, as offered by GUD
    Filters; as opposed to a warranty that will replace only the filter and not cover
    the damage done to the vehicles' engine.
3. Always ensure that the brand you fit to your vehicle meets or exceeds the 
    original equipment vehicle specification, as GUD Filters do.

FACT:

South African conditions may require shorter oil service intervals than those in Europe and the East. This is because of our higher dust concentration, extreme changes in altitude, our vehicles’ higher working loads and poor fuel quality.

GUD Oil Filter (Z88G) vs Sub-Standard Oil Filter

GUD Oil Filter

Seal : Rotates to reduce radial stress

Date Code : Every filter is identified by a date code for traceability

  

Sub-Standard Oil Filter

Seal : Fixed in retainer, cannot rotate and could tear when tightening filter

Date Code : None - no traceability of stocks as required by effective quality systems

Thread : Clean thread

 

Thread : Rough thread - difficult to fit

By-pass valve : Opens at O.E. rated pressure

 

By-pass valve : Opens well below specification meaning that the filter is in total bypass allowing dirty oil to enter the engine continuously from the moment it starts up

End cap adhesive : Evenly spread for effective sealing

 

End cap adhesive : Uneven and insufficient adhesive causes leaks across the filter

Filter paper : 60 pleats x 22mm pleat height

 

Filter paper : 58 pleats x 16mm pleat height

Paper area : 245 520mm2

 

Paper area : 157 760mm2 (36% less filtration area which results in hugely shorter filter life)

Pleat join : Melitta joined (Mechanical pressured seam join)

 

Pleat join : No pleat join (folded over) causes dirty oil to enter the engine instantly
