iPower 4-inch 190 CFM Inline Duct Fan Combo — 4-inch Carbon Filter, 8 ft Ducting, Quiet 48 dB

This all-in-one kit combines a 4" inline duct fan rated at 190 CFM, a 4" x 12" activated-carbon filter, eight feet of aluminum ducting, stainless clamps and a replaceable pre-filter to create a ready-to-install exhaust solution. The fan delivers steady airflow while the filter's activated RC 412 Australian carbon media traps odor molecules and particulates as air moves through the honeycomb-style core. Everything ships together for a straightforward upgrade or initial setup in grow tents, closets, or small HVAC circulation jobs.

How does this combo reduce odors and airborne contaminants?

The filter uses a dense activated carbon bed to adsorb volatile molecules and common odors as air is pulled from the tent by the inline fan. The fan maintains continuous airflow so incoming air passes through the filter media, where contaminants are retained while clean air exits the system.

• Activated RC 412 Australian carbon media captures odor-causing molecules.
• Honeycomb core increases surface contact for more efficient adsorption.
• Pre-filter traps hair and larger particulates to prolong carbon life.
• Reversible flange lets you orient the filter to suit your space.

Will a 4" 190 CFM fan move enough air for my grow tent?

A 190 CFM rating is well suited to small grow tents or single-plant enclosures where compact equipment is required. Calculate your tent's volume (length × width × height) and aim for several air exchanges per minute; this fan supports frequent exchanges in modest volumes.

• 190 CFM peak airflow for small-to-medium tents or cabinets.
• Quiet operation at approximately 48 dB for low-noise setups.
• Compact 4" flange fits common ducting and fittings.
• Use duct length and bends modestly to preserve airflow performance.

What materials and durability features are included?

The kit pairs corrosion-resistant components and temperature-tolerant ducting so it performs reliably in indoor horticultural environments. Stainless steel clamps and a flame-retardant aluminum duct with a protective coating increase longevity while the fan housing is built for continuous operation.

• 8 ft uninsulated aluminum ducting with corrosion-resistant wire helix.
• Temperature range rated from 0 to 185°F (-18 to 85°C).
• Two stainless clamps secure connections and resist rust.
• Replaceable pre-filter recommended every six months for best results.

How easy is this system to install and maintain?

The combo is designed for fast setup: connect the filter to the fan, attach the ducting and clamp, then mount the assembly inside your tent or enclosure. Routine upkeep is limited to swapping the pre-filter periodically and replacing the carbon filter when airflow or odor control declines.

• Plug-and-play assembly requires basic clamps and fasteners.
• Reversible flange lets you orient filter without special tools.
• Pre-filter protects the carbon core and extends service life.
• Simple cleaning and replacement schedule keeps performance steady.

Who is this for: Growers, hobbyists and small-space ventilations needs who want a compact, combined exhaust and filtration solution. If you run a small grow tent, a cupboard-style grow, or need discreet odor control in limited space, this iPower bundle offers a balanced mix of airflow, filtration, and easy installation. It’s not intended for large commercial systems; for bigger rooms or multi-tent setups, consider larger fans or multiple units to maintain adequate air exchange and filtration performance.
