State of the Art Manufacturing

All our manufacturer's production facilities are equipped with the latest state of the art machinery. From the parts list the components are produced on computerized numerically controlled (CNC) machines to minimize throughput time and achieve precise tolerances.

On completion of the equipment, a fan test run and final inspection is carried out.

All work is conducted by highly skilled production personnel.

The ability to work with many materials is due to the high levels of welding expertise in the Company, continuously updated by an ongoing commitment to training and the achievement of appropriate welding certificates.

Modern test facilities are used to develop and test even large scale fans and blowers prior to shipment up to and including motor powers of 600 HP.

Quality re-assured

Recent customer surveys show that more than 90% of customers recognize our products as being of excellent quality with very long life expectancy. Customer complaints (including customer errors and incomplete deliveries) are consistently less than one percent of total shipments.

Warranties

Reinforcing their commitment to total quality all of our suppliers offer a 12 month warranty after shipment on all fans and 3 years on heat exchangers.

1) It identifies who is responsible for what.
2) It allows for three different levels of construction: Type A, B, and C.
3) It is general in nature to allow different fan manufacturers to comply using alternative methods.
4) It provides disclaimers and warnings to users concerning residual risks.
5) It does not require qualification testing.

While not explicitly stated, AMCA 99-0401 is limited to applications for which the explosive materials are present in a sealed ducted airstream, but not present on the outside of the fan housing. For all classes of spark resistance, bearings and electrical devices (motors, sensors, etc.) are not allowed in the direct airstream. From the lowest level of protection to the highest, the classifications of spark resistant construction are:

Type C: The fan is designed so that if the impeller or shaft comes loose and shifts during operation, two ferrous parts will not come into contact.
Type B: In general, this requires a nonferrous impeller and a nonferrous rubbing ring around the shaft hole. Also, extra locking systems are required to prevent the fan impeller, shaft, and bearings from shifting.
Type A: This requires a nonferrous airstream. Also, the extra locking systems are required as in Type B.

All spark resistant types require the fan to be electrically grounded so as to prevent static electricity from building up. The end user is responsible for installing the ground strap.

A common material used by fan manufacturers in achieving spark resistance is aluminum. The AMCA standard provides a warning that aluminum rubbing on rusty steel will create sparks. It is the end user’s responsibility to ensure that steel surfaces are suitably coated, and that fans are kept clean from iron oxides. The AMCA standard allows fans to be constructed of any material which has “demonstrated ability to be spark resistant.” Metals containing less than 5% iron are allowed. Although aluminum is the most common construction material, copper, brass, Monel, and other metals are used where corrosion and temperature limit the suitability of aluminum. NOTE: Stainless steel does NOT comply.

Non-metallics are often avoided as a construction material for the fan impeller due to the potential for buildup of static electricity. Some fan wheels are constructed of fiber reinforced plastic (FRP) which has an electrically conductive surface coat. This coating should be electrically grounded to the shaft.

The AMCA standard is widely used in the United States, and is referenced by other standards. An equipment specifier need only state “AMCA Spark Resistant Type B” to convey a multitude of fan design requirements. The standard is effective in that the risks of fan-induced explosion can be dramatically reduced without excessive cost additions.

Internationally there are other standards which are used. At the time of writing this article there is a developing European “CEN” standard. This standard is attempting a much more comprehensive approach to this subject. While the AMCA standard does not claim to make fans truly “explosion proof,” the CEN standard may well make that claim. It could do this by including many more considerations that may be relevant in reducing the likelihood of an explosion, including:

- Fan modifications required to accommodate the presence of explosive environments outside the airstream.
- A more limited set of construction materials.
- Specifications on design durability and other mechanical aspects.
- Requirements on gas stream sealing, motor construction, bearing design and shafting design.
- Fan qualification testing.
- Operating temperature limits.
- Maintenance and cleaning requirements.
- Limiting the ability of foreign materials to enter the fan (by use of screens).
- Use of larger internal clearances for the fan rotor.
- Other safety equipment and sensors.

If adapted internationally, this standard would likely reduce the likelihood of explosions. However, it would also add to the first cost, installation cost, and the operating cost of a fan system.

Until such time as a uniformly accepted code clearly defines all specifications of a “safe” system, system designers must decide on their own. The fan manufacturer can usually accommodate the fan modifications necessary to comply with more comprehensive specifications. However, the system designer must assess the risks and identify what is needed. Fan manufacturers usually are not in a position to advise what modifications are necessary to make a system acceptably safe for every possible environment.

The AMCA spark resistant standard is adequate for the vast majority of all fans used in potentially explosive environments. However, where the hazards are extremely severe, consider adding more detailed specifications to reduce the potential for explosion to exceptionally low levels.
