iPower 4 Inch Inline Ventilation Kit — 195 CFM Fan, Carbon Filter, 8ft Duct, Variable Speed

The iPower 4-inch inline ventilation kit is a complete grow-tent exhaust solution that combines a 195 CFM inline fan, 4" activated carbon filter, 8-foot PVC ducting, variable speed control and hangers for reliable air exchange and odor reduction.

Designed for small grow tents, closet gardens and compact ventilation projects, this bundled set delivers controlled airflow, carbon filtration and flexible duct routing in one box. The fan and filter match a 4-inch duct size for an efficient, low-profile installation. Included accessories—PVC ducting, clamps, a variable controller, and ratchet-style hangers—make setup straightforward and let you tailor airflow to temperature and humidity conditions.

How much airflow and noise can I expect from the 4-inch inline fan?

The fan is rated for approximately 195 CFM at its maximum speed and runs at about 2500 RPM, producing a low baseline noise level near 30 dB in typical conditions. That CFM is suitable for single small tents or confined spaces needing steady exhaust. Noise remains modest thanks to the compact motor and inline design.

• Rated airflow: ~195 CFM
• Speed: ~2500 RPM
• Power: 28 W at 120 V, 60 Hz
• Noise level: ~30 dB (quiet operation)

What filtration and odor control does the carbon filter provide?

The included 4-inch carbon filter uses high-grade activated carbon to reduce odors and airborne contaminants as air passes through. It features a pre-filter to capture dust and larger particles, protecting the inner carbon and extending service life. The filter’s compact flange and hook design make hanging and connecting to ducts simple.

• Carbon media: Australian RC412 activated carbon
• Airflow capacity: up to 220 CFM rating on the filter housing
• Includes pre-filter and hanging hook
• Flange length: 12-inch filter body for secure ducting

How will the ducting, controller and hangers help me install and control the system?

The kit includes an 8-foot, 4-inch PVC thermoplastic duct with aluminum-foil inner lining to prevent light leaks while resisting heat and corrosion. Two clamps secure duct connections; adjustable ratchet hangers support the fan and filter up to 150 lb. The variable speed controller gives three running modes plus OFF, and a fast-response humidity sensor updates every 10 seconds for basic environmental monitoring.

• 8 ft x 4" PVC ducting with aluminum foil interior
• Two duct clamps included for airtight connections
• One 350 W variable speed controller: OFF, HIGH, MED, LOW
• Two 8-ft ratchet hangers rated to support up to 150 lb

What operating ranges and durability specs should I expect?

Materials were chosen for longevity in indoor horticulture environments: the PVC duct tolerates temperatures from -22°F to 212°F (-30°C to 100°C) and resists corrosion. The fan draws about 0.45 A at 120 V, while the humidity/temperature monitor covers 14°F–122°F (-10°C–50°C) and 10%–99% relative humidity. These ranges suit typical grow-tent climates and allow reliable day-to-day operation.

• Duct temperature range: -22°F to 212°F (-30°C to 100°C)
• Humidity range: 10%–99%; temperature sensor: 14°F–122°F
• Fan current: ~0.45 A at 120 V
• Compact, corrosion-resistant construction for extended use

Who is this for: growers, hobbyists and DIY ventilators looking for a compact, all-in-one 4-inch exhaust solution. If you need quiet, controllable airflow plus basic odor reduction in a small tent, closet or compact HVAC application, this iPower kit bundles the fan, carbon filter, ducting and accessories to get you running quickly without sourcing parts separately.
