Item Description
Broad Line of Inline Duct Fans!
Inline Duct Fans are ideal for remotely venting equipment rooms and closets, projector enclosures, built-in cabinetry, racks and more. The fans generally move significantly more air, are mounted remotely so they are quieter and out of the way.  The fans are very powerful and efficient motor delivers an impressive amount of airflow that will handle the most demanding applications.

We offer the most comprehensive line of inline duct fans, from more basic 'retail' versions to highly advanced professional units.  We also have various sizes to fit the respective markets perfectly.

Description of Units


This unit is ideal for applications where it may be challenging to run high voltage and can instead use this unit and control is with our low voltage controllers.  This unit utilizes 3" ducting which is easy to install in 4" walls and directly connects to our various duct boxes.

      Common Description/Features of the Below Units
  • The number in the SKU signifies the duct size
  • All of these fans are High Voltage Fans
  • The fans features 2 selectable speeds except EC versions are Progressive Speed
  • Units feature an IP44 harsh environment rating

Description and Specifications by Model


This unit is the high voltage version of the 3" fan and is good for more basic applications like projector or enclosure cooling applications and mates directly to our various duct boxes.  This unit it generally recommended for DIY or for more budget oriented applications.
    • Specs: 120V AC / 2 Speed / Amps: .42 Low Speed/.5 High Speed / Watts: 25/29 / RPM: 2550/2750 / CFM: 67/76 / Noise: 21/26db / Pressure: 114/129Pa / Life: 50k hrs / Ball Bearing / IP44

This unit is also for DIY/budget applications but with more airflow than the 3" unit.  This is ideal if simply require more airflow or if pulling air from more than one location.  Just as an example, with using a wye (Y) fittings you can vent from the ceiling and down a wall into a cabinet easily.
    • Specs: 120V AC / 2 Speed / Amps: .45/.55 / Watts: 30/38 / RPM: 2100/2600 / CFM: 78/100 / Noise: 26/31db / Pressure: 105/125Pa / Life: 50k hrs / Ball Bearing / IP44
    As compared to above, this is ideal if simply require more airflow when pulling air from more than one location.  
      • Specs: 120V AC / 2 Speed / Amps: .47/.58 / Watts: 31/40 / RPM: 2100/2600 / CFM: 107/128 / Noise: 26/31db / Pressure: 115/140Pa / Life: 50k hrs / Ball Bearing / IP44
    NOTE:  When we start getting into higher airflow units, it should be noted that maximum airflow is the not always the solution, more is not always better...   In general it is not necessary to 'aggressively cool', it is more important to 'properly cool' and that is our focus.  This is one of the most fundamental principles in a system that operate quietly and effectively and are designed and built to last...  It all begins with the very basics, spacing equipment properly, providing 'spot cooling' units appropriately... then moving onto venting systems...

    We have now moved onto the Pro versions.  The primary difference with the pro versions is the housings.  The above units utilize an ABS housing while the Pro versions are polypropylene.  Poly houses are better in attics and harsher environments.   This unit is perhaps the most common unit due to the amount of airflow but also the ease of installation (4" ducting is most common)... 
      • Specs: 120V AC / 2 Speed / Amps: .22/.54 / Watts: 28/30 / RPM: 1850/2200 / CFM: 97/117 / Noise: 26/31db / Pressure: 131/156Pa / Life: 50k hrs / Ball Bearing / IP44

    This unit very simply is just a larger version than above and would only be used in very demanding situations.
      • Specs: 120V AC / 2 Speed / Amps: .49/.58 / Watts: 53/65 / RPM: 1850/2550 / CFM: 241/312 / Noise: 29/33db / Pressure: 245/300Pa / Life: 50k hrs / Ball Bearing / IP44

    EC FansWe definitely saved the most exciting for last as the EC Units (Electronically Controlled) are high voltage fans but are controlled via low voltage.  This means that our low voltage controllers can be used to control the fan speed and in a linear progression.  Traditionally high voltage fans have been difficult to control and even more 'clunky' when do connect a controller (hum, wobble...).  Due to the units running only as required, at a speed matched to demand, the units are very efficient, very quiet, and ideal for most applications.

    This is simply the 4" version of the Electronically Controlled fan which can be used with the TC-ALTv2, TC-ASC units, and the TC-TSTAT-12 controllers.
      • Specs (Based on Full Speed): 120V AC / Variable Speed / Amps: .28 / Watts: 16.5 / RPM: 2250 / CFM: 117 / Noise: 28db / Pressure: 156Pa / Life: 50k hrs / Ball Bearing / IP44

    This is simply the same as above, just the 6" version which means higher airflow.
      • Specs (Based on Full Speed): 120V AC / Variable Speed / Amps: .28 / Watts: 16.5 / RPM: 2250 / CFM: 311 / Noise: 36db / Pressure: 156Pa / Life: 50k hrs / Ball Bearing / IP44
