RDM 3S/FS
Vertical discharge centrifugal roof fan with frequency-controllable IEC standard motor, protection class IP55, suitable for temperatures up to approx. +120°C. Tightly closed housing made of corrosion-resistant aluminium with two opposing, upward-facing discharge openings. These outlets are sealed against all weather influences by self-closing flaps when not in use. The base frame is made of galvanised steel sheet. The housing is designed so that the discharge sections can be folded out and the fan section can be tilted. This makes maintenance and inspection easy. Incl. fitted isolating switch.
