General Specification Description of CRDV 180-315
IPF/Colasit Fans are made according to ISO 9001-2000 and tested according to ISO 5801standards. This is the international standard for Air and Flow testing and is comparable to the rigor or the AMCA standards.
IPF/Colasitpolypropylene fans are made from polypropylene with a special additive from Simonaof Germany. This material can be classified as flame retardant under the European standard DIN 4102 B1. (See enclosed sheet for more details on DIN 4102 B1.)
The manufacturing process is vacumn formed thermoplastics which ensures more precise moldings of housing and impeller.
There is no metal exposed in the air stream. The internal motor is effectively shielded by a corrosion resistant motor plate made from SS or PP at the buyers option.
The inline and roof mounted fan series is available in only PPs and can be used in applications to temperatures up to 160-170 degrees.
PPs is more flexible than PVC and therefore easier to work with and less prone to be damaged by installation or maintenance error.
There are three sizes for the Housings.
CRDV 200 which is the same housing used for the CRDV 180
CRDV 250 which is the same housing used for the CRDV 225
CRDV 315 which is the same housing used for the CRDV 280
These fans use the same heavy gauge radial impellers developed for our Utility Style Centrifugal fans.
CRDV 180 has a radial impeller with flat blades.
CRDV 200-315 have forward curved blades
