RAM Mix-Flow Inline Fan Z2/250 - 1030m3/hr (10") - Industrial-Grade Extraction on a Budget
Best for: Growers who want a step up from entry-level ducting fans without paying for a premium EC-motor unit.
Our thoughts
RAM has built a solid reputation on delivering dependable, quiet-running fans at a sensible price, and the Z2 mixed-flow range is a good example of that. It's not the newest EC-motor technology on the market, but it's a straightforward, well-built AC fan that does the core job of shifting air properly. Good value for growers stepping up from a basic starter fan.
The RAM Mix-Flow Inline Fan Z2/250 is a 10-inch (250mm) mixed-flow duct fan rated to move 1030 cubic metres of air per hour (roughly 606 CFM). It's a switched two-speed fan, optimised by its mixed-flow impeller design for higher static pressure and quieter operation than a basic axial fan of the same size - useful when you're pulling air through a carbon filter and a run of ducting, both of which add resistance.
It comes with an integral mounting bracket for easy hanging or fixing in place, and is fitted with an IEC power socket for a straightforward plug-in connection. The housing is a durable plastic design intended to help dampen fan noise, and the motor is thermally protected to guard against overheating during long runtimes.
How it compares
The mixed-flow inline fan category spans everything from budget AC units to premium variable-speed EC fans.
- Against premium EC-motor fans like the Vortex Powerfan or Systemair's own RVK EC range, the Z2 uses a simpler AC motor with two fixed speeds rather than infinitely variable EC speed control - the trade-off is a lower price for less granular control.
- Against basic own-brand axial duct fans, the mixed-flow design and thermally protected motor put it a step up in build quality and pressure performance.
- Against similarly priced fans from PrimaKlima, output and features land in a broadly comparable bracket - RAM's long track record in hydroponic ventilation is the main point in its favour.
A dependable mid-tier fan for growers who want more than entry-level performance without paying EC-fan prices.
Usage guidance
Straightforward to install as part of a standard extraction setup.
Positioning
Mount using the integral bracket, either in-line with your ducting run or directly attached to a carbon filter, and support the weight properly rather than relying on the ducting alone.
Speed selection
Use the two-speed switch to match output to your setup - the lower speed is generally quieter and sufficient for smaller tents, while the higher speed suits larger spaces or when pulling through a filter and longer duct run.
Power connection
Connect via the fitted IEC socket using a standard IEC lead, making it easy to wire into a fan speed controller if you're running one.
Technical specifications
- Duct size: 10" (250mm)
- Maximum airflow: 1030 m3/hr (approx. 606 CFM)
- Speed settings: 2 (switched)
- Fan type: Mixed-flow, AC motor
- Motor protection: Thermally protected
- Housing: Durable plastic, acoustic-dampened

Who this is for
- Growers upgrading from a basic starter extraction fan
- Anyone running a 10" carbon filter setup who wants reliable static pressure performance
- Budget-conscious growers who don't need variable EC speed control
Best suited to standard tent and grow-room extraction rather than ultra-quiet, whisper-level setups.
Our take
This is a well-built, dependable mixed-flow fan from a brand with a long history in grow-room ventilation. It won't match a premium EC fan for silent running or infinite speed adjustment, but for the price it delivers solid, genuinely useful airflow.
Proper kit at a price that makes sense for anyone stepping up their extraction without splashing out on EC-motor pricing.
