Fans - circular duct
Fan RVK series is designed for installation in duct. RVK fans are equipped with backward curved ilopatkami and external rotor motors. Fan housing is made of plastic reinforced with fiberglass PA6. Fans can be used in wet environments due to high casing tightness and thanks to protection class IP44 terminals. RVK fans for easier installation supplied with a mounting bracket. The fan speed can be continuously controlled thyristor or a 5-step transformer. Motor protection against overheating is ensured by built-in thermal contacts with automatic reset.
Fans type RMQ are centrifugal fans, which can be used to mounting into the circular duct. For mounting square flange on the wall (extraction), suction is connected via circular duct. They are designed to transport air without mechanical particles, which could cause abrasion or imbalance of impeller. Fans are suitable for space without dangerous of explosion, should not be exposed to direct effects of the weather. Fans can be instal in horizontal or vertical position. It is possible to regulate the transformer or electronic speed controllers reducing stress. Fans should be stored in covered and dry warehouse.
