Whether in kitchen stoves, ovens, climate-controlled cabinets, food and plate warmers or in medical devices, sterilisation units and drying ovens: ebm-papst hot-air blowers provide perfect air performance in both household and commercial applications. Some of the reasons for this include optimum air volumes and a long service life, as the function of the motor is not impaired by the hot air being moved. In short: They render extremely quiet and reliable service.
Hot-air blowers usually consist of an asymmetric shaded-pole motor with one shaft end brought out, which carries a hot-air impeller made of stainless steel or die-cast aluminium and can also feature a catalytic coating. The motor itself contains bearing shields with a special mounting option that enables the fan to be installed outside the hot area. The impellers are usually very narrow and backward curved. For commercial ovens, the tried-and-tested external rotor motor is used as a single-phase AC motor, three-phase motor or GreenTech EC motor. The great advantage of hot-air blowers with GreenTech EC technology: intelligent sensors and programming ensure that they always deliver optimum air volume.
Pyrolytic ovens are a real boon to cleanliness. Though they relieve the housewife or househusband of messy work, the hot-air blower does not get any relief at all. It must withstand temperatures up to 500 °C over a lengthy period of 1–2 hours without any decrease in output or function.
Our RRM 42 hot-air blower has been developed for exactly this challenge, which it passes with flying colours – thanks to exceptionally effective strong insulation, which provides ideal protection for the motor. Even with all these strengths, the blower remains particularly low-profile.
