- Features & Benefits
Design AppealIdeal for roof spaces and / or where space is at a premium.
Low NoiseEach unit is acoustically lined, therefore the breakout noise levels are low.
Ease of InstallationAll 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.
PerformanceHigh efficiency low tonal noise backward curved centrifugal impellers are directly driven by an EC external rotor motor, designed to be non overloading and provide high performance characteristics.
Easy MaintenanceAccess to the fan and motor is by an easily removable panel for maintenance when required.
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.
ReliabilityMotor and Impeller manufactured by Ziehl-Abegg providing increased reliability.
MountingEach unit is supplied with integral mounting brackets.
Motor ProtectionAll SQT units have integral thermal overload protection which prevents the motor from overheating.
Tested To The Very Latest StandardsSQT units are tested to ISO 5801:2007 (airside performance) and to BS 848 Pt 2:1985 (sound performance) at Elta Fans own test facility, meaning accurate, up to date information on performance and noise data that can be relied upon.
Quality AssuranceAll units are designed and manufactured with procedures as defined in BS EN ISO 9001: 2008.
WarrantyEach SQT 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 wrap around folded 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 twin range of units have an EC 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. Electrical connection shall be via an IP55 terminal box mounted on the side for easy customer connection.
ImpellersHigh efficiency low tonal noise backward curved centrifugal impeller, dynamically balanced to ISO 14694 Grade G6.3 and directly driven by the motor to provide a smooth airflow through the unit.
Quality ManagementUnits are to be designed and manufactured with procedures as defined in BS EN ISO 9001:2008. All SQT units are to be tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
