Mammoth TT & Mammoth Filter Extraction Kit

Mammoth TT & Mammoth Filter Extraction Kit — Complete Inline Fan & Carbon Filter System for Grow Tents

Best for: Growers who want simple, complete air extraction without faffing about with separate components

The Mammoth TT & Mammoth Filter Extraction Kit is a complete inline ventilation system designed to remove hot, humid, stale air from your grow space and replace it with fresh, cooler, CO2-rich air. It pairs a twin-speed Mammoth TT inline fan with a matched Mammoth carbon filter, black combi ducting, and duct clips—everything pre-matched and ready to install. No hunting for compatible sizes, no separate controller needed, no missing parts. Just a solid, reliable extraction kit at a price that doesn't rinse your budget.

How it compares

The Mammoth TT sits in the budget-to-entry-level segment of grow room extraction kits.

• Pre-matched fan and filter—no guessing about compatibility or airflow losses
• Twin-speed mechanical control included; no separate speed controller needed (unlike many budget competitors)
• Premium RC48 Australian carbon filter—same quality as higher-priced kits, fraction of the cost
• Complete ductwork and clips included—literally everything you need
• Available in six sizes (4-inch to 12-inch) to fit small, medium, and larger spaces

Compared to premium brands like AC Infinity with WiFi controllers and smart automation, you're trading app control for simplicity and a lower price. If you want basic, reliable extraction with no fuss, this is the one.

Usage guidance

The Mammoth TT extraction kit works by drawing hot, stale air out of your grow space and allowing fresh air to come in—a process called air exchange. Here's how to use it:

Basic setup
Connect the carbon filter to the inlet end of the fan using duct clips. Connect ducting to the outlet. Hang the system at the top of your grow area (where hot air rises naturally) and run the ducting to an external point or window. Position your setup to create negative pressure—pulling stale air out faster than it can be replaced, which draws fresh air in from vents or passive intakes at floor level.

Speed control
Use the low speed setting during dark periods or when you need quieter operation. Switch to high speed during peak heat or if humidity climbs. This basic two-speed control gives you enough flexibility to adjust for seasonal changes or different growing phases without needing a separate fan speed controller.

Small to medium grows (up to 1.2m x 2.4m)
Passive intake (open vents or gaps) usually pulls enough fresh air in naturally. The extraction fan does the heavy lifting by pulling warm, humid air out.

Larger grows (1.2m x 2.4m and above)
Consider adding a second, smaller Mammoth TT fan on low speed for active intake. This balances the extraction and prevents negative pressure from being too aggressive, which can stress plants and reduce CO2 availability.

Sizing rule of thumb
Aim for a fan that exchanges the air in your grow space roughly every 1–3 minutes. For a 4ft × 2ft tent (about 40 cubic feet), you'd want a fan rated around 40 CFM or higher. Use the fan size chart to match your grow space dimensions.

Technical specifications

• Available sizes: 4-inch, 5-inch, 6-inch, 8-inch, 10-inch, 12-inch
• Airflow (12-inch model, examples): 1750 m³/h (low speed) to 2206 m³/h (high speed)
• Fan speed: Twin-speed mechanical control (low and high settings)
• Filter type: Mammoth Carbon Filter with premium RC48 Australian carbon
• Filter bed depth: 50mm
• Filter lifespan: Approximately 2 years (varies with grow room conditions and fan speed)
• Ductwork: Black combi ducting (plastic-lined, tear-resistant)
• Accessories included: Three duct clips for secure connections
• Installation: Ready to run with no additional wiring required

Who this is for

• First-time extraction users stepping up from passive ventilation
• Budget growers who want complete kit without buying separate components
• Growers replacing old or failing extraction systems on a reasonable budget
• Anyone prioritising odour control and simple, reliable temperature/humidity management
• Small-to-medium grow space operators (tents and small rooms)
• Growers who want proven equipment without premium brand pricing

Particularly well suited to growers who value simplicity and completeness over smart features—you get extraction that works without needing to learn app controls or programming.

Our take

This is a proper extraction kit at a price that makes sense. It's pre-matched, it's complete, and the carbon quality is genuinely good—RC48 Australian carbon is the real deal, and you're getting it without the premium markup. The twin-speed control is a nice touch, giving you immediate flexibility without forcing a separate controller purchase.

If you're setting up extraction for the first time or replacing old kit, this is worth picking up while stock lasts. It handles heat, humidity, and odour control without overcomplicating things. Does exactly what it should, day in, day out.
