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.
