Core Product Features
Main Structural & Performance Advantages
· Ultra Compact Integrated Design: Small body size, lightweight, easy ceiling concealed installation, does not occupy indoor usable space.
· Ultra-Low Noise Mute Operation: Minimum operating noise as low as 24dB, optimized mute fan wheel and air duct structure, suitable for bedrooms, offices and quiet rest spaces.
· Multi-Stage Composite Filtration System: Standard primary + medium-efficiency dual filter layers, purification efficiency over 95%, effectively intercept dust, pollen, bacteria and particulate pollutants in outdoor air.
· Two-Speed Adjustable Speed Control: High/low two wind speed gears, freely switch ventilation volume according to indoor crowd density and air quality demand.
· Galvanized sealed cabinet structure: Anti-rust, airtight, effectively prevent air leakage during air supply, stable long-term continuous operation.
Working Principle
Adopt positive pressure one-way fresh air supply mode:
Outdoor air is sucked into the unit, filtered step-by-step by multi-layer filter media to remove pollutants.
Purified fresh air is evenly delivered into the room to form slight indoor positive pressure, pushing turbid indoor exhaust air out through door/window gaps, realizing invisible whole-house air replacement without independent exhaust pipeline.
Typical Application Scenarios
· Civil: Residential apartments, villas, basements, newly renovated houses (remove formaldehyde and decoration peculiar smell), bedrooms, study rooms
· Commercial: Small offices, classrooms, kindergartens, cafes, entertainment rooms, shops without good natural ventilation windows
· Matching demand: Closed spaces with poor natural ventilation, spaces requiring quiet operation, small-space constant fresh oxygen demand
Model Selection Case Reference
Take FP350 as example: Suitable for 60㎡ office with 6–8 staff members, meeting 30m³/h per person ventilation standard, solving poor ventilation and turbid air in windowless office areas, realizing 24-hour invisible fresh air replacement.
Usage Restrictions
· Only for ceiling concealed mounting, not for wall-mounted exposed installation.
· Fixed standard power supply: 220V 50Hz single-phase household/commercial electricity.
· Ambient operating temperature range: -10℃ ~ 45℃, avoid long-term direct sunlight exposure.
· Filter maintenance cycle: Primary filter can be cleaned repeatedly every 1–2 months; medium-efficiency filter is disposable, replace every 6–12 months based on local air quality.

Q1: What is the difference between this FP one-way fresh air fan and bidirectional total heat recovery fresh air ventilator?
A1: FP series is only for fresh air supply (positive pressure air intake), no independent exhaust pipeline or heat exchange core, smaller size and lower cost; bidirectional model realizes simultaneous air supply & exhaust with energy recovery, suitable for high energy-saving demand spaces.
Q2: What filtration layers are standard equipped for FP series? What purification effect can be achieved?
A2: Standard matched primary + medium-efficiency double filter system, purification efficiency over 95%, which can filter outdoor dust, pollen, PM2.5, bacteria and peculiar smell effectively.
Q3: What are the core advantages of this model compared with similar one-way fresh air machines?
A3: Ultra-small integrated body for easy ceiling installation, industry-leading low noise (minimum 24dB), two-speed adjustable wind speed, lightweight structure, simple filter disassembly and maintenance.
Q4: What installation method is adopted? Will it occupy indoor ground space?
A4: Concealed ceiling hoisting installation, the whole machine is hidden inside the ceiling, only ventilation pipe outlets are exposed, no occupation of indoor usable floor area.
Q5: What power supply standard does FP series adopt? Can it be used with ordinary household sockets?
