Product: TerraBloom ECMF-100-R, Quiet 4" Inline Duct Fan with Wireless Remote Speed Controller, Air Tight Metal Casing, Energy Efficient EC Motor. Heating and Cooling Booster and Exhaust Blower For Growing
Brand: TerraBloom
Color: Black
Description: Frequently Asked Questions:

What is included in set with ECMF-R fan?

1.Fan pre-wired with a 6.5ft long cable and grounded 3-prong plug. 2. Wireless Remote Speed Controller. 3.Installation Hardware (Screws and Anchors).

How to adjust ECMF-R series fan speed?

Each ECMF-R fan is supplied with a remote speed controller. Remote controller works from up to 50 FT range and allows to select 6 speeds from OFF position to MAX SPEED. When using the controller for the first time, it has to paired with the fan by pressing and holding “+” or “-“ button for 3 seconds. Fan speed pre-sets available via remote speed control:

OFF = 0% Output

Level 1 = 10% Output

Level 2 = 25% Output

Level 3 = 50% Output

Level 4 = 65% Output

Level 5 = 85% Output

Level 6 = 100% Output

Will Other Speed Controllers work with ECMF-R fan?

No. If you need a replacement of ECMF-R fan speed controllers please contact TerraBloom’s customer service.

What are the requirements for the fan's operating environment?

ECMF-R fan can be operated in the environments with temperatures between 15°F(-10°C) to 140°F (60°C) and humidity levels not exceeding 90%. ECMF-R series fans have IPX4 IP Rating.

What type of ball bearing used in ECMF-R series fans?

ECMF-R fans are built with heavy-duty dual ball bearings rated for up to 70,000 hours of operation.

Can ECMF-R fans be used for boost airflow in heater ducts?

ECMF-R can be installed in heating ducts with most modern home furnaces, however, it is important to ensure that the air temperature in the duct is not over 140 °F. Please note, fire places and fire-based heaters supply air at over 140 °F, which will cause ECMF-R fan to trigger overheat safety switch and/or cause deformation of the impeller.

Product: AC Infinity CLOUDLINE S4, Quiet 4” Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics
Brand: AC Infinity
Color: Black
Description: Inline Duct Fan

The duct fan system is designed to quietly cool AV equipment rooms and closets, and to ventilate various air circulation and exhaust projects. Features an inline speed controller utilizing PWM-technology. Contains a mixed-flow design and an EC-motor for a quiet and high static-pressure performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one duct fan unit, one inline speed controller, installation manual, and all necessary mounting hardware.

Precise Speed Controller

The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppress voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight-speed options are available with a power switch, and backup memory. This S4 model can be connected to the smart controller of the CLOUDLINE T4 to share the same programming and power source.

Quiet and Energy Efficient Design

The inline fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.
Designed to ventilate grow tents, transfer heating/cooling to rooms, circulate air, exhaust odors, and cool AV racks.
Features an 8-speed manual controller utilizing PWM. See T-Series for temperature and humidity controls.
Mixed flow design combined with an EC-powered motor for a truly quiet and energy efficient performance.
Kit also includes corded AC power adapter, installation manual, and all necessary mounting hardware.

Product: AC Infinity CLOUDLINE T4, Quiet 4” Inline Duct Fan with Temperature Humidity Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics
Brand: AC Infinity
Color: Black
Description: Inline Duct Fan

A smart inline duct fan designed to quietly ventilate hydroponic grow rooms, boost heating/cooling to rooms, circulate fresh air, exhaust projects, and cool AV closets. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. Includes an intelligent controller that features advanced programming and functions. Complete kit includes one duct fan unit, one thermal controller, one corded thermal probe, two duct clamps, installation manual, and all necessary mounting hardware.

Intelligent Controller

The controller can be programmed to adjust fan speeds to respond to varying high and low temperatures, and humidity. For ventilation applications, the controller can be set to run continuously or triggered to run at customizable speeds when given power, due to its backup memory capability. Additional features include a countdown timer, alarm system, and eco-mode. Includes detachable 12-foot precision water-resistant probe. This smart controller can power and control the CLOUDLINE T4 along with a CLOUDLINE S4 to share the same programming.

Quiet and Energy Efficient Design

Unlike common duct fans that use an AC-motor which are loud and unmanageable, this duct fan features a DC or EC-motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed-flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids, and performs well even in harsh environments.
