Application
1. Dwell Mix fans are featured with wide capabilities and high performance of axial and centrifugal fans and are specifically designed for supply and exhaust ventilation of premises requiring high pressure, powerful air flow and low noise level.
2. The fans are compatible with round air ducts from Ø 100 to 315 mm. Exhaust ventilation systems based on the Dwell Mix100 fans are the best solution for ventilation of bathrooms and kitchens and other humid premises as well for ventilation of flats, cottages, shops, cafes, etc.
Design
1. The casing is made of high-quality durable plastic.
2. All the models may be equipped with a regulated timer with turn-off delay adjustable from 2 to 30 min.
3. The removable impeller and motor block with a terminal box is fixed to the casing assembled with the spigots by means of special clamps with latches. This makes the fan maintenance fast and easy. The fan maintenance does not require total disassembling. Just pull out the central block from the casing and perform required servicing.
Mounting
1. The fans are suitable for mounting at any angle and point of the system. Several fans may be installed inside one system.
2. Several fans may be installed inside one system:
a. parallel mounting to increase air flow;
b. in series mounting to increase operating pressure;
3. The fan case is equipped with a flat mounting plate to attach the fan to the wall.
4. The mounting box may be installed in any position to facilitate mounting and wiring.
Motor
1. The models of Mixed Flow series are equipped with a single phase motor and are available in single or two speed modifications. Some dimension types are available with a more powerful motor.
2. The motors have thermal overheating protection to prevent the motor overload.
3. The ball bearings extend the motor service life up to 40 000 hrs. at non-stop operation.
4. The motor has IP X4 ingress protection rating.
Speed Control
1. The double-speed motors are controlled with a built-in switch (V option) or an external switch for multi-speed fans (available upon separate order).
2. An integrated speed controller (option P), an external TRIAC or autotransformer speed controller (available upon separate order) are used for smooth speed control when connected to the maximum speed terminal.

Operational Logic
1. Set the desired air temperature (set point of the thermostat) with the thermostat control knob. Set the required minimum impeller speed (air flow) with the speed control knob. The motor switches to maximum speed (maximum air flow) as the temperature reaches and exceeds the set temperature set point. The motor switches to the pre-set speed as the temperature drops down below the set temperature point.
2. To avoid the frequent motor switching, e.g. when the temperature in the supply air duct is equal to the threshold value, the switching delay time is activated.
There are two switch delay patterns for various cases:
1. The temperature sensor-based switch delay (U option): the motor switches to higher speed as the air temperature exceeds 2°C above the set thermostat set point. The motor revers to the pre-set lower speed as the air temperature drops below the thermostat set point. This pattern is used to keep air temperature to within 2°C. In this case the fan switches are rare.
2. The timer-based switch delay (U1 option): as the air temperature exceeds the set thermostat set point, the motor switches to higher speed and the switch delay timer is activated for 5 min. The motor reverts to lower speed as the air temperature drops down below the thermostat set point and only after the timer countdown. This pattern is used for exact air temperature control. The fan changes its speed more often as compared to the temperature sensor-based switch delay, however the minimum timer interval is 5 minutes.

Compact inline airflow with stronger pressure and quieter control.
Dwell MIX 100–315 is a mixed flow inline duct fan built for projects where a basic axial fan is not enough. It combines the compact format of an inline fan with stronger airflow and better pressure behaviour, making it suitable for kitchens, bathrooms, laundries, utility areas, apartments, villas, shops, cafés, and other ducted ventilation layouts.
Mixed flow performance
Designed to combine axial-style airflow with better pressure handling, so ventilation stays more dependable once ducts, bends, and resistance enter the system.
NMB Japan ball bearing motors
Positioned for stronger long-term confidence, smoother everyday duty, and dependable ventilation performance across residential and commercial applications.
Service-friendly body
The motor-and-impeller block can be removed without dismantling the whole casing, helping maintenance stay faster and easier once the fan is already installed.
Flexible installation logic
Suitable for mounting at any angle, usable at different points of the duct route, and deployable in parallel for airflow or in series for pressure.
Need help choosing the right MIX size?
Talk to Dwell Air for product selection, duct-route suitability, and ventilation sizing support for your kitchen, bathroom, utility, or commercial project.
Dwell MIX is suitable for supply or exhaust ventilation in spaces where air has to move through an actual duct path instead of just discharging through a grille.
One fan range. Many modern ventilation layouts.
Dwell MIX is especially useful where the route is compact but airflow still needs to remain stable through ducts, bends, and moderate resistance.
Homes and apartments
Useful where bathrooms, kitchens, utility rooms, or compact exhaust routes need a more capable inline fan than a simple room-mounted option.
Retail and hospitality
Suitable for shops, cafés, and similar interiors where concealed inline placement and steady ventilation performance matter.
Short to medium duct routes
Well suited for compact ventilation runs where resistance is higher than an open grille setup, but full centrifugal fan architecture is not required.
Supply or exhaust duty
The range is positioned for both supply and exhaust ventilation, giving more layout flexibility depending on the project requirement.
Not sure whether MIX, axial, or centrifugal is right?
Dwell Air can guide you based on duct length, bends, pressure resistance, and the type of space you are ventilating.
Dwell MIX uses a mixed-flow impeller design that combines axial and centrifugal airflow behaviour inside a compact inline body.
Air enters the inline body
The fan sits within the duct route and pulls or pushes air directly through the system instead of only ventilating at the wall grille.
The mixed-flow impeller accelerates the air
The impeller geometry is designed to combine the straightforward movement of axial flow with stronger pressure capability, helping performance stay useful once resistance rises.
Air continues through bends and duct resistance
This is where MIX becomes more useful than a basic axial fan. As ducts get longer or include bends, a more pressure-capable inline fan helps preserve actual airflow.
The central block stays service-friendly
The removable motor-and-impeller block allows inspection and servicing without dismantling the full casing from the installed route.
| Feature | What it helps with |
|---|---|
| Mixed-flow inline construction | Stronger airflow and more useful pressure in a compact body. |
| Removable motor + impeller block | Easier maintenance after installation. |
| Flat mounting plate | Simpler attachment to wall or support points. |
| Any-angle mounting suitability | More flexibility in real project layouts. |
| Parallel / series installation logic | Allows scaling airflow or operating pressure where needed. |
