No blower no air! In industrial processes one blower can often supply several air heaters in parallel. Our durable and maintenance-free blowers are a result of uncompromising quality standards and decades of experience. SILENCE, Leister’s mid-range blower, is very quiet during operation at 61 dB(A). Developed to withstand operating conditions with air intake temperatures of 100° C to 200° C (212 °F to 392 °F). Delivers optimum & effortless performance in ambient temperatures up to 75° C (167 °F).
SILENCE
Very quiet operation with 61 dB(A). Large air volumes and can be installed in all positions.
