Smoke-spill Applications
The APS Series has been tested to meet the air performance and high temperature test requirements of Standards AS/NZS1668.1:1998 and AS4429:1999; both tests are mandatory. For advice on smoke-spill wiring requirements refer to the above standards. For advice on smoke-spill wiring requirements refer to the downloadable brochure. Elta Fans smoke-spill range available.
Hazardous Fume Applications
AP Series fans can be made to accommodate requirements for corrosive fume and explosion risk applications. Special coatings and alternative materials, such as stainless steel, are available as well as increased safety motors and anti-static impellers. Our sales engineers are able to assist with requirements, which must be specified at time of quotation.
Protection
Internal thermal protection can be provided as an optional extra.
Testing
Airflow tests to BS848:Part 1, 1980 (for our 315 to 1000mm diameter models) and ISO 5801:1997 (for our 1250 to 2000mm diameter models) Noise tests to BS848:Part 2, 1985.
Specification
Construction
Casings are hot-dip galvanised mild steel, or pre-galvanised steel.
Impellers
Impellers can be GRP (standard) or aluminium. Anti-static blades for hazardous applications up to 1400mm diameter are also available.
Motors
The fans are built with a squirrel cage induction motor with ball bearings. The motor requires an electricity supply of three phase to suit a wide range of voltages and frequencies.
Motors to meet Ex e, Ex d, Ex nA and Ex tD Standards can be fitted.
