1. Safety warning
•This ventilation fan can be used by adults and persons
with reduced physical, sensory or mental capabilities
or lack of experience and knowledge if they have been
given supervision or instruction concerning the use
of the appliance in a safe way and understand the
hazards involved.
•To avoid the risk of electrical shock, or injury to persons,
always make sure that the fan is unplugged from the
electrical outlet before relocating, servicing, or cleaning
the product.
•Never touch moving parts when the fan is on or the
impeller is moving.
•If installed without ducting, use a protective grille and
install the fan away from the reach of children and pets.
•The fan contains no user-serviceable parts inside. Refer
to the manufacturer for service.
•Do not pull the power cord too hard or hold the fan by
the power cord. If the power cord is damaged or frayed
it must be replaced by the manufacturer or a qualified
service person.
•Keep this instructions manual for future reference.
2.1 Product contents
2.2 Fan applications
Our fans generate powerful directional airflow required
for ventilation in indoor plant cultivation. This product is
built to be used as a component for FabricAir®Rack Flow
System. Any other usage is unauthorized and shall void all
warranty and liability.

3.1 Operating environment requirements
•This fan is intended and rated for indoor use only.
•Operating temperature range: -5°F – 140°F (-20°C –
60°C). Humidity range: 0-90%.
•Not suitable for applications in close proximity to open
flame (wood or gas burning) furnaces. Temperatures
over 140°F can cause permanent damage to electronic
components.
•Not suitable for environments with flammable
or hazardous substances, explosive gases or
chemical dust.
•In environments with high dust or debris content, use
a pre-filter to prevent dust, grease and other foreign
substances from building up on the fan blades. Debris
buildup leads to mechanical damage, increased
vibration and noise.
3.2 Installation
•Inspect fan for shipping damage before installation.
Ensure that the fan blade rotates freely without
touching the housing.
•Securely attach the fan to a hard surface using the
pre-installed mounting bracket and screws designed
for the surface type in your application.
•Do not install on hollow drywall. Mount to hard surfaces
(i.e..wood, concrete, metal).
•If used with securely installed carbon filters, it is
acceptable to install the fan on top of the filter’s duct
collar. Secure the connection with a duct clamp.
3.3 Application tips
•The ducting has a strong effect on the air flow,
noise and energy use of the fan. Use the shortest,
straightest duct routing possible for best performance,
and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce
energy loss and inhibit mold growth. Fans installed
with existing ducts may not achieve their rated airflow.
•A duct of matching size with the fan inlet and exhaust
is recommended for best performance.
•Install the fan at least 6ft above the floor to keep it out
of reach of children and pets. For added safety use
metal grills/guards to keep fan’s moving parts from the
reach of children and pets.
•After installation, perform a test run to confirm that the
fan operates as intended. A speed controller must be
connected to the fan before power up.
•Once powered on, the fan blade should rotate freely
and accelerate gradually.
•If excessive noise is present, verify that there are no
foreign objects (duct pieces, screws, etc.) touching the
fan blade. Secure installation to the FabricAir®Rack
Flow system fan bracket is key to avoiding vibration
and excessive noise.

4.1 Fan operation with speed controller
•You must use a speed controller in order to operate
this fan. We include a digital speed controller in set
with the fan.
•Locate the speed controller port under a screw-on
plastic dust cap on the side of the fan.
•Controller – 8 speed digital speed controller. Each press
of a button on the controller increases the speed by 1
level or 12.5%. Speed level 1 = 12.5% of maximum speed,
Level 2 = 25%, Level 3 = 37.5%, Level 4 = 50%, Level
5 =62.5%, Level 6 = 75%, Level 7 = 87.5%, Level 8 = 100%
(maximum speed).
4.2 Optional speed controllers
•PWM controllers (Arduino, Raspberry Pl, etc.) use
the frequency range of 15-32 kHz and voltage range
of 10-12 V.
•If used with a third-party speed controller, use the
provided TRRS 3.5 mm connection wire or a DIY speed
controller wire with pin outputs to connect the fan with
the controller
•Refer to the illustration below for a description of pin
outputs on the DIY speed controller wire.
4.3 Speed controller wiring diagram
4.4 Speed controller wire
•Insert speed controller
wire jack fully into the
connection port until it
clicks into position. Secure
in place with a plastic
locking nut located on the
speed controller wire.
•This fan is rated for continuous use and can be operated 24/7.

7.1 Note on fan output and static pressure
•The CFM rate stated on the fan and in the tables below is a
“nominal” airflow rate and is applicable only when no additional
equipment is attached to the fan.
•When you attach any equipment to the fan (ducts, vent caps,
filters, splitters, elbows, etc.) you are introducing static pressure,
an obstacle in the path of the airflow. This will cause the final
amount of airflow delivered by the fan to be lower than the
nominal airflow.
•Each duct fan has a maximum pressure rating which equals to
the maximum static pressure it can counteract in order to move
a certain volume of air.
•A pressure drop is the amount of static pressure introduced by a
filter or any equipment attached to the fan.

5. Fan maintenance
•Use a damp cloth to remove dust and any debris build
up from fan components every 6-12 months
•To avoid mechanical damage, do not apply pressure to
the fan blades.
6. Warranty
FabricAir®Rack Fan series fans are covered by a 2-year
warranty from the date of purchase against any defects
in workmanship or materials. Under warranty, the fan will
be either replaced or repaired and must be accompanied
by proof of purchase. The warranty doesn’t apply to any
damage caused by excess heat or humidity, misuse in
harsh industrial environments, physical damage or normal
wear and tear of the unit, any other than a component for
FabricAir®Rack Flow System usage is unauthorized and
shall void all warranty and liability.
