S Series Bidirectional Flow Fresh Air Ventilator
The S series bidirectional flow fresh air unit is a thin ceiling-mounted ventilation device with dual air inlet centrifugal fan structure, realizing simultaneous fresh air supply and indoor stale air exhaust. It features slim cabinet, ultra-low noise operation and two-speed adjustable airflow, widely applicable to residences, schools, basements, shopping malls, hotels and internet cafes, with 5 airflow specifications ranging from 200 to 1000 m³/h.
Core Product Features
Structural & Performance Advantages
· Bidirectional Air Exchange Integrated Design: Single unit completes fresh air intake and dirty air exhaust at the same time, realizes air circulation between indoor and outdoor, no need to match two separate single-way fans, saves installation space and overall project cost.
· Dual Air Inlet Centrifugal Fan System: Multi-blade centrifugal impeller + double suction air duct + high-efficiency volute, generates higher static pressure for long-distance duct layout, greatly reduces operating noise, minimum noise only 33dB.
· Ultra-Thin Integrated Cabinet: Compact slim body, lightweight structure, easy concealed ceiling hoisting without occupying indoor usable space; detachable shell for convenient fan cleaning and filter maintenance.
· Two-Speed Adjustable Control: High / low two wind speed gears, freely switch airflow volume according to indoor passenger flow and air quality demand.
· Sealed galvanized sheet housing: Anti-rust and airtight, effectively prevent air leakage during air supply & exhaust, support stable 24-hour continuous operation.
Working Principle
Dual-circulation bidirectional ventilation:
Outdoor fresh air is sucked into the unit via the air supply port, conveyed into each room through ventilation ducts.
Stale indoor air containing CO₂, peculiar odor and pollutants is drawn back into the machine via the exhaust port and discharged outdoors, forming complete indoor-outdoor air circulation without relying on door/window gaps for exhaust.
Typical Application Scenarios
· Civil: Family houses, villas, bedrooms, study rooms, basements, newly renovated rooms
· Commercial: Supermarkets, shopping malls, hotels, internet cafes, classrooms, kindergartens, small closed offices
· Matching demand: Closed spaces with poor natural ventilation, quiet environments requiring low noise, venues needing independent exhaust pipeline layout
Usage Restrictions
· Installation method: Concealed ceiling hoisting only, wall-mounted exposed installation is not supported.
· Standard power supply: 220V 50Hz single-phase AC household & commercial electricity.
· Operating ambient temperature: -10℃ ~ 45℃, avoid long-term direct sunlight exposure.
· Maintenance reminder: Regularly disassemble the cabinet to clean fan impellers and replace matched filter screens to prevent dust accumulation from increasing noise and reducing airflow.

A1: S series integrates independent air supply and exhaust channels inside one unit, which can send fresh air and discharge dirty air simultaneously with complete air circulation. Single-way models only supply fresh air and exhaust air through door/window gaps, without independent exhaust pipeline.
A2: It uses dual air inlet centrifugal multi-blade fan wheel with optimized volute air duct design, the minimum low-speed operating noise is only 33dB, suitable for quiet spaces such as bedrooms and hotel rooms.
A3: Equipped with two-speed control of high and low gears, users can switch the airflow according to the number of indoor people and air pollution level.
A4: Ceiling concealed hoisting installation, the whole machine is hidden inside the ceiling, only ventilation pipe outlets are exposed, which will not occupy usable indoor ground area.
A5: Standard 220V 50Hz single-phase AC power supply, fully matching common household and commercial socket standards.
A6: Widely used in supermarkets, hotels, internet cafes, schools and other commercial closed spaces, also applicable to residential villas and basements with poor natural ventilation.
A7: The integrated cabinet is detachable, convenient to take out the internal fan and filter screen for regular cleaning and replacement, with low maintenance difficulty.
A8: This standard S series is basic bidirectional air exchange model without total heat exchange core, focusing on complete indoor and outdoor air circulation; if energy recovery function is required, you can select FE series total heat recovery fresh air ventilator.
A9: The standard configuration is 220V 50Hz. We support customized motors and control panels with special voltages for large export container orders to adapt to local power grid standards.
A10: Each unit is attached with full English installation and operation manual. We supply complete spare parts including fan motors, two-speed control switches and matched filter screens, and provide professional ceiling pipeline layout design guidance and fault troubleshooting technical support for wholesale customers.
