GROW1 8" Inline Fan

The GROW1 8" Inline Fan is a durable, high output ventilation fan designed for larger grow tents, grow rooms, and greenhouses that need substantially more airflow than smaller inline fans can provide.

Producing 745 CFM, it delivers strong air exchange for mid to large size growing spaces, while its thermally protected AC motor is built to run reliably over long duty cycles.

• Airflow: Powerful 745 CFM Output
• Motor: 2,530 RPM Thermally Protected AC
• Build: Ceramic Coated Metal Housing
• Setup: Brackets + 8 Foot Power Cord Included

The fan’s motor operates at 2,530 RPM and includes thermal protection, which helps guard against overheating during continuous operation. This makes the GROW1 8" Inline Fan a practical choice for growers who run ventilation systems for extended periods throughout a growing cycle.

Like the rest of the GROW1 lineup, this fan uses a ceramic coated metal housing rather than lightweight plastic. This construction is designed to resist corrosion, withstand humid grow room conditions, and hold up to repeated use over time.

The fan comes with mounting brackets and an 8 foot prewired power cord, allowing for a straightforward installation without needing to source additional hardware or wiring.

Whether mounted for intake or exhaust, the GROW1 8" Inline Fan is designed to integrate easily into new or existing 8 inch ducting systems, making it a dependable addition to larger grow tent, grow room, or greenhouse ventilation setups.

745 CFM Airflow

The GROW1 8" Inline Fan delivers 745 CFM of airflow, suitable for larger grow tents, grow rooms, greenhouses, propagation rooms, workshops, and general ventilation applications where more airflow is needed.

Thermally Protected AC Motor

The internal AC motor operates at 2,530 RPM and includes thermal protection. This helps guard the motor against overheating during long duty cycles, supporting more dependable performance in ventilation systems that run for extended periods.

2,530 RPM Motor Speed

The motor’s rated speed of 2,530 RPM is designed to provide the airflow needed for effective large scale ventilation while working in tandem with the fan’s housing and blade design to maintain efficient performance.

Ceramic Coated Metal Housing

The fan housing uses a ceramic coated metal construction rather than plastic. This is designed to provide greater resistance to corrosion, better durability in humid grow room environments, and longer service life under repeated use.

Built for Grow Room Conditions

Indoor growing environments often involve elevated humidity and repeated temperature changes. The ceramic coated housing is intended to hold up to these conditions better than uncoated or plastic alternatives, helping the fan maintain performance over time.

High Capacity 8 Inch Design

The 8 inch duct size provides significantly more airflow capacity than the smaller GROW1 fans, making it well suited for larger grow tents, grow rooms, greenhouses, and other spaces where more air exchange is needed.

Intake or Exhaust Applications

The GROW1 8" Inline Fan can be installed for either intake or exhaust airflow. Common configurations include exhausting warm air from a larger tent or room, bringing in fresh air, supporting larger carbon filtration systems, and maintaining general air exchange.

Grow Room Ventilation

The 745 CFM output makes this fan well suited for larger indoor garden spaces where smaller fans may struggle to maintain adequate air exchange. It can help support heat removal, humidity control, fresh air exchange, and environmental stability. Actual ventilation needs will depend on the size of the space, lighting heat load, ducting configuration, and filtration used.

Greenhouse and General Ventilation

Beyond dedicated grow rooms, the fan can also be used for larger greenhouse ventilation, workshops, and other spaces where reliable 8 inch airflow is needed.

Easy Installation

Mounting brackets are included to simplify installation into an 8 inch ducting system. The fan is designed to be positioned inline with minimal additional hardware required.

8 Foot Prewired Power Cord

An 8 foot prewired power cord is included, giving installers flexibility in fan placement without needing to be positioned directly next to an outlet.

Recommended Installation Practices

• Confirm the connected ducting is 8 inches in diameter.
• Install the fan in the correct airflow direction.
• Secure the fan using the included mounting brackets.
• Support connected ducting independently when necessary.
• Keep duct runs reasonably short.
• Minimize unnecessary bends.
• Keep intake and exhaust openings unobstructed.
• Keep electrical connections dry.
• Clean connected filters regularly.
• Disconnect power before maintenance.

Ventilation Planning

Fan performance can be affected by duct length, duct diameter, carbon filters, sharp bends, intake restrictions, and exhaust restrictions. The rated 745 CFM represents the fan’s output rating. Actual airflow within an installed system may be lower depending on overall system resistance.

Ducting Setup

For stronger ventilation performance: use properly sized 8 inch ducting, keep ducting as straight as practical, avoid crushing flexible ducting, minimize sharp turns, secure connections with appropriate clamps, and seal unwanted air leaks.

Carbon Filter Compatibility

The fan can be incorporated into compatible 8 inch filtration systems. When pairing with a carbon filter, confirm the filter uses compatible 8 inch connections, check the filter’s airflow rating against the fan’s output, account for the added airflow resistance, and support the filter independently when appropriate.

Cleaning and Maintenance

Routine Cleaning

• Disconnect the fan from power.
• Inspect the intake and exhaust openings.
• Remove accumulated dust and debris.
• Inspect connected ducting.
• Clean filters according to their manufacturer instructions.
• Confirm mounting hardware remains secure.

Housing Care

• Wipe the ceramic coated housing with a soft, dry or lightly damp cloth.
• Avoid abrasive scrubbing tools that could damage the coating.
• Keep the housing free from built up dust and debris.
• Inspect the coating periodically for wear or damage.

Duct Maintenance

• Inspect flexible ducting periodically.
• Remove obstructions.
• Check for loose connections.
• Repair damaged ducting.
• Remove unnecessary bends where practical.

Fan Inspection

Periodically inspect mounting brackets, the power cord, fan housing, duct connections, intake opening, and exhaust opening. Stop operation if electrical components or the housing show significant damage.
