Why VT501-WiFi for single-room fresh air

95% Recovery

Ceramic heat exchanger

Recovers up to 95% of thermal energy, so fresh air arrives without throwing away conditioned air.

Smart Control

Remote or WiFi operation

Choose the standard remote model or the WiFi model with Tuya app control, CO2 monitoring and automation.

Dual Filter

HEPA + activated carbon

Multi-stage filtration reduces pollen, dust, PM and outdoor odors before supply air enters the room.

Quiet Room

Under 30 dB operation

A brushless DC motor and sound-sealed design suit bedrooms, nurseries and home offices.

3 Modes

Fresh, exhaust and cycle

Fresh Air, Exhaust and 65-second Cycle modes give practical control over room ventilation.

DIY Fit

Single-hole wall install

No central ductwork required. It installs through an exterior wall with a telescopic duct and room-side panel.

How to select the right VT501 version

VT501 comes in three control versions for single-room fresh-air ventilation with heat recovery: VT501 (base), VT501-WF (WiFi) and VT501-MS.

Pick the airflow stage

Four stages (20 / 48 / 54 / 60 m³/h) suit bedrooms, offices and small rooms. Match the stage to room size and occupancy.

Check wall / tube depth

The installation tube fits 250–500 mm wall thickness. Measure the actual opening before ordering.

Choose the control

Base remote control or WiFi version with app control. Confirm which is required for the project.

Where this single-room HRV fits

VT501 / VT501-WF / VT501-MS is a room-by-room ventilation route for bedrooms, offices and other spaces where a central ventilation system is not the selected installation approach.

Fit boundary: For whole-building balanced ventilation, confirm whether a central ERV or multi-room design is required.

Frequently asked questions

Can this replace a central ERV?

It is mainly a room-by-room retrofit option. For whole-building balanced ventilation, confirm a central ERV or multi-room design.

What must be checked before order?

See the order checklist above: control version, wall thickness, airflow stage, power supply and quantity.

Are the listed values final for every version?

No. The values are source-backed from PDF p.6; confirm the exact version and order configuration for quote review.

100% pre-shipment inspection

Every batch undergoes functional and dimensional checks so that every unit arrives ready for installation: ceramic core fit, filter placement, remote and WiFi response, airflow mode switching, wall tube sizing and noise verification.

Hardware warranty support

In the rare event of a material defect or mechanical failure under standard operation, a straightforward replacement service protects your project timeline.

Before you order: confirm checklist

  • Control version: VT501 (remote) or VT501-WF (WiFi)
  • Wall thickness and installation tube length (250–500 mm)
  • Airflow stage (Sleep / I / II / III) and operating mode
