Overview
All metal inline centrifugal fans which are ideally suited to a wide range of commercial and industrial applications. They provide the ideal solution for high performance requirements in low airflow, medium pressure systems.
Features and Benefits
Easy Installation
All models are designed for direct connection to standard diameter flexible or rigid circular ducting with 25mm long spigots for ease of connection. The integral mounting bracket provides a fast, simple approach to fixing the fan in position.
Space Saving
A compact casing design, combined with high performance makes the product ideal for ceiling void mounting.
Efficient Performance
The single inlet, single width backward curved centrifugal impeller is designed to be non overloading and self cleaning ensuring efficiency.
Warranty
Each VL has a 12 month warranty.
Specification
Casing
VL casings have a galvanised pressed sheet steel construction, providing a robust, long lasting and corrosion resistant casing. The inlet and outlet spigots area minimum of 25mm long to enable the installation and fixing to circular rigid, or flexible ductwork. All VL units are to be supplied complete with integral mounting brackets manufactured from galvanised sheet steel for horizontal or vertical mounting arrangements.
Motors
All motors are to be highly efficient external rotor motors; matched to the aerodynamic performance of the impeller. Motors have sealed for life ball bearings to enable the fan to be mounted at any angle. Motors are protected to IP44 with Class F insulation; suitable for speed control and ambient operating temperatures up to +50°C with built in thermal overload protection. Non self-resetting thermal cut-outs are fitted in accordance with EN60335-2-80. Motors are wound for 230V/1Ph/50Hz/60Hz supply. Electrical connections are made by an IP54 terminal box fitted to the outside of the fan casing.
Impellers
All impellers are single inlet backward curved centrifugal type. Impellers are balanced to ISO 14694 Grade G6.3.
Control
Speed control shall be via stepped transformer or 3 speed switch dependant on model.
Quality Management
Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001. All Versaline VL units are to be tested to ISO 5801 (airside performance) and BS848 Part 2 (sound performance).
