## Description

Frequently Asked Questions:What is included in set with ECMF fan?1. Fan pre-wired with a 6.5ft long cable and grounded 3-prong plug. 2. Variable speed controller. 3. Speed controller cable (16ft long). 4. Installation Hardware (Screws and Anchors).How to adjust ECMF series fan speed?Each ECMF fan is supplied with a variable speed controller. Speed controller is attached to the fan via the supplied cable. When connected, supplied speed controller allows users to select any speed between 0-100% of output according to the preferred use/noise level. If the speed controller is disconnected, ECMF fan will automatically work at 100% output. Speed Controller connects to the fan via a 16 Ft wire, which is independent from the power cable. Will other Rheostat Speed Controllers work with ECMF fan?Speed controllers designed for AC motors, such as typical rheostat speed controllers, will not work with ECMF series fans. If you need a replacement of ECMF fan speed controllers please contact TerraBloom’s customer service. What are the requirements for the fan's operating environment?ECMF 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 series fans have IPX4 IP Rating. What type of ball bearing used in ECMF series fans?ECMF fans are built with heavy-duty dual ball bearings rated for up to 70,000 hours of operation.Can ECMF fans be used for boost airflow in heater ducts?ECMF 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 110 °F. Please note, fire places and fire-based heaters supply air at over 140°F, which will cause ECMF fan to trigger overheat safety switch and/or cause deformation of the impeller.

## Questions & Answers

**Q: Can this be used to move grinding and welding smoke?**
A: If it is just smoke, then it won't be an issue for the fan. But you need to make sure there won't be any hard particles going into the fan, as they can damage the blade and the motor.

**Q: In a pets grooming salon dogs hair is flying all over the place when we blow dry the dogs. Can this unit be used to suck the dogs hair to a canister?**
A: Hello,

Unfortunately, this fan will not work well for your application. Pet hair will be getting stuck inside the unit and getting wrapped around the impeller and fan's rotor, which can potentially increase chances of overheating and malfunction. If you still decide to us it for this application you need to ensure that there is a filter placed before the fan which will catch all of the hair before it reaches fan's parts.  This somewhat defeats the purpose, as you want the hair to go into a canister and not to be trapped on the filter surface before the hair reaches the fan. Hope this helps.

Best regards,
TerraBloom

**Q: Does this fan have a dc motor? and is it pwm controlled?**
A: This fan has a EC motor, which is a subtype of DC motors. Key difference is that it doesn't require a DC adapter since the conversion of electricity current happens inside the fan instead of DC adapter. The fan is controlled using Potentiometer technology and it yields exactly the same results as PWM.

**Q: Is the shipping discreet?**
A: Hi Daniel, You will need to select an option to gift wrap your order so that Amazon ships it in a additional box. We do not package or ship our fans directly to Amazon customers, it is done by Amazon staff from Amazon warehouses.

Best regards,
TerraBloom Team
