No blower no air! In industrial processes one blower can often supply several air heaters in parallel. Our durable and aintenance-free blowers are a result of ncompromising quality standards and decades of experience. SILENCE, eister’s mid-range blower, is very quiet during operation at 61 dB(A). It delivers high air lows and can be installed in all orientations.
