The Helios FM 200 EX is a flexible sleeve specifically engineered for use with explosion-proof ventilation fans. It serves as a vibration-damping connector between the fan and ductwork, effectively preventing structure-borne noise transmission and accommodating minor installation tolerances. Constructed with a durable PVC fabric cuff, the FM 200 EX offers both flexibility and resilience in demanding environments. It includes two hose clamps for quick and secure mounting, making it ideal for use in hazardous areas where explosion protection is required.
