Filter Supply Inline EC – FSDEC56

Filter Supply Inline ECFantech EcoRange Energy Efficient Fans

Performance Curve - FSDEC56


The EC Series of Inline Filtered Supply Units has been designed to provide filtered outside air to a range of applications where direct fresh air intake is not possible or practical.

They incorporate the latest state-of-the-art EC motor technology. The range features fully integrated, infinitely variable speed control which eliminates the need for external VSDs, current overloads and motor phase protection. They are an energy saving solution and are most efficient where conditions vary during the course of the day.

  • Robust, yet lightweight galvanised steel construction
  • Mixed-flow impeller with high performance blade geometry
  • Pure-V washable G4 filters on the fan discharge side that can be easily accessed via a removable side panel
  • EC motor features reverse polarity protection, locked rotor protection and soft starting
  • No additional electrical protection such as contactors are required
  • All models supplied standard with 0-10V control input
  • Supplied with TDF flanges as standard for inline mounting or installed with an external grille for flush to wall mounting
Galvanised steel housing with material filters on the discharge side of the fan. Industry standard 35mm TDF profile flange for easy connection to ducting.
Type - electronic commutated (EC) motor.
Electricity supply - 200-277V single-phase, 50/60Hz or 380-480V three-phase, 50/60Hz
Integrated EC-Controller providing infinite speed control
Bearings - sealed-for-life, ball.
Internal Thermal Protection
Integral thermal overload protection is supplied as standard.
Air flow tests based on ISO 5801.
Noise tests based on ISO 13347-3.
Performances shown are based on clean filters.
As air flow will be affected by room pressurisation, care should be taken to ensure adequate air relief is provided.
Special Note

Pure-V filters

The Inline Filtered Supply Unit incorporates Airepure Pure-V filters that are pleated for extra durability and will hold their shape without the need of a wire support metal cage.
Pure-V panel filters are washable.

The filters should be checked during cleaning for wear or damage and replaced when necessary. They can be removed via the side access panel on the discharge side of the fan.

Differential Pressure Switch

A differential pressure switch can be used to provide indication that the filter needs maintenance

Airepure Pure-V filters are tested with an efficiency of G4 to standard EN 779:2002.
