• weatherproof lid fitted
• air intake or discharge via weather cowl or louvre fitted with birdmesh guard

Specification

• fan options of forward curved belt driven, backward curved belt driven, or backward curved direct drive plug style impellors.
• fan impellers are statically and dynamically balanced in accordance with VDI2060 and ISO 1940/1. Supplied as standard with pre-greased sealed for life bearings having L10 life of 20,000 hours at peak performance
• standard motors of squirrel cage induction type, totally enclosed, fan cooled, suitable for 3ph, 50Hz electricity supply
• motors with IP55 protection and Class F rating
• high efficiency EC motors available as an option, depending on duty requirement
• fan and motor connected via vee belt drive, prealigned and tensioned
• fan and motor are mounted on a common chassis frame isolated from casing via open coil spring anti-vibration mounts and flexible connector fitted to fan discharge. Transit bolt fitted to prevent damage during transport
• LPHW batteries are constructed from copper tubes mechanically bonded onto aluminium fins supplied with standard BSP male connectors. Option of vinyl coating (copper and electro-tinned copper also available). The coil casing is in galvanised sheet steel
• moisture eliminator plates manufactured from polypropylene fitted where necessary. Coils are mounted on slide-in channels to aid removal
• electric heater batteries for single and 3 phase operation are manufactured from sheathed rod elements with an integral manual reset thermal cut-out for wiring into control unit. It is recommended that fan run-on timer is incorporated in controls to prevent possible heat damage
