GUARDIAN/GUARDIANX SERIES
NEMA 4 or 4X FILTER FANS KNP40FL
DESCRIPTION
Kooltronic has expanded its line of filter fans to include models offering the versatility and security of indoor or outdoor use. All Guardian Series Filter
Fans have a NEMA 4 Rating. The GuardianX Series Filter Fans, with a NEMA 4X Rating, are offered with a Stainless Steel Shell. The
Guardian/GuardianX Series Indoor/Outdoor Filter Fans are a perfect choice for dissipating high heat loads economically. These models are available
in a variety of sizes, voltages and protection levels.
The new Guardian/GuardianX Series Filter Fans offer the same convenience, versatility and reliability as the Advantage Series Filter Fans with the
added protection of a NEMA 4 or 4X Rating, making these models an excellent choice for telecommunications and other outdoor applications.
COMPONENT CHARACTERISTICS
■
Standard airflow direction is from the outside to the inside of the cabinet.
■
Filters are stable up to 100ºC and 100% rh. (Filters are necessary in order to maintain NEMA 4 or 4X Rating).
■
Filters guarantee a continuously high level of protection according to EU4, with a 94% separation efficiency according to DIN 24185 Standard.
NOTE: Filter media is washable about 10 times.
■
With filters, dust capacity is particularly high (620 g/m2), which reduces maintenance.
ACCESSORIES AND OPTIONS
■
Other supply voltages, both AC and DC, are available on request.
■
Filter fans can be supplied with reversed airflow direction (from inside the cabinet to outside). To order, add "R" after series number. Example:
KNP40RFL.
■
Depending on the request and quantity, parts can be supplied in different colors.
■
Filter-Hood Assembly (Recommended) (P/N: KNPA60FL).
