Product catalog summary

Overview: The document provides technical specifications and details for SlimVent plate and cased axial fans, models SPW and SCW. These fans feature metal impellers, a compact motor design, and are speed controllable. They are designed for high efficiency and low noise levels.

Specifications:

Casing: Made from mild steel with epoxy paint coating. SPW models are white (RAL 9010), and SCW models are grey (RAL 7032).
Impeller: Dynamically balanced metal impellers. Sizes up to 500 mm use mild steel blades, while sizes 560 and 630 mm use cast aluminum. The hub is cast aluminum, suitable for temperatures from -30°C to +70°C.
Motor: External rotor motor with die-cast aluminum casing, protected to IP 54. Includes thermal contacts for motor protection and radio suppression. Sealed for life ball bearings.
Motor Protection: Thermal contacts are standard and should be connected to a motor protection unit. For size 630, a suitable protection unit is required.
Electrical Connection: SPW models have terminals in a terminal box at the rear of the motor. SCW models have terminals in an IP 55 terminal box on the casing.
Guard: SPW models include a motor side wire guard. SCW models do not include a guard but it is available as an accessory.
Speed Control: All models are speed controllable with a 5-step auto transformer and electronic speed controllers.
Installation: Compact design allows installation at any angle or position.
Sound Levels: Sound levels are 'A' scale weighted levels LWA and LPW.

Technical Data:

Various models are listed with specifications such as motor amps, wiring diagrams, maximum air flow, and protection types.
Dimensions and sound levels for each model size are provided.

Accessories:

Electronic Speed Controller (ESA): Provides variable speed control with built-in fuse and adjustable lowest speed. Protection IP 65.
5 Step Transformer Speed Controller (TSW): Offers five fan speeds with robust casing. Protection IP 54.
Mounting Feet (MK): For fixing axial cased fans to various surfaces.
Flange (FR): Spigotted flange made of galvanized steel.
Anti Vibration Mounts (SDD 1.5): Reduce noise and vibration transmission.
Circular Silencer (RDS): For direct connection to cased axial fans, acoustically lined with mineral wool.

Notes: All Helios components fit standard nominal duct diameters, and the ducting can be rigid or flexible, made from various materials.
