- Features & Benefits
All units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.All models are designed for direct connection to standard diameter flexible or rigid circular ducting with 50 mm long spigots with EPDM rubber U shaped seals for ease of connection.
Material strengthA robust, yet lightweight unit with a galvanised sheet steel casing treated internally with a Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining with a fire resistant polymeric coating.
PerformanceHigh efficiency backward curved centrifugal impellers are directly driven by an AC or EC external rotor motor, designed to be non overloading and provide high performance characteristics.
MountingEach unit is supplied with integral mounting brackets.
Design appealIdeal for very shallow ceiling voids and / or where space is at a premium.
Quality assuranceAll units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.
WarrantyEach SH has a 12 month warranty.
CasingThe robust 1.2mm galvanised mild steel sheet casing, is treated internally with a Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining with a fire resistant polymeric coating. The casing is specially manufactured using integral motor mounting plates to provide additional rigidity for the casings. Each casing provides spigots to suit standard circular ducting. EPDM (Ethylene Propylene) rubber U shaped seals (being ozone and UV stable) are used to ensure a good seal back to the duct that is to be attached. A removable lid is provided as a standard feature to facilitate ease of maintenance and cleaning.
MotorsThe single range of units may have either an EC or AC external rotor motor fitted as standard. The motor contains sealed for life bearings. Thermal Class of motors to THCL 130 or 155 dependent on size. Manufactured by Ziehl-Abegg providing increased reliability. All motors are suitable for use in ambient air conditions up to +60°C.
ImpellersHigh efficiency low tonal noise backward curved centrifugal impeller, dynamically balanced to ISO 14694 Grade G6.3 and directly driven by the motor.
Quality ManagementUnits are to be designed and manufactured with procedures as defined in BS EN ISO 9001:2008. All SH units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
