Panasonic S-3650PF3E PACi NX PF3 3.6–5.0kW Adaptive Ducted Indoor Unit – 150Pa, nanoe X, R32
Hurry up, only 10 items left in stock.
The Panasonic S-3650PF3E is a 3.6–5.0kW PACi NX PF3 adaptive ducted indoor unit that can be installed horizontally in a ceiling void or vertically in a cupboard or plant space, serving multiple rooms through ductwork.
With up to 150Pa of external static pressure it drives longer duct runs than a low-static unit, and the rear- or bottom-entry return air option plus an improved drain pan for both orientations give real installation flexibility. A drain pump is included. nanoe X Generator Mark 2 purification is effective even over duct lengths up to 10 metres.
The PF3 supports single, twin, triple and double-twin systems, IoT and CONEX control, low-temperature configurations for cold rooms, and quick Bluetooth commissioning with the CZ-RTC6BL controller. Matching supply plenums (CZ-56DAF2, CZ-90DAF2, CZ-160DAF2) are available.

Good to know
This is a split-system component that contains or connects to R32 refrigerant, so it must be installed and commissioned by an F-Gas registered engineer. It is supplied as a single unit – pair it with a compatible Panasonic outdoor/indoor unit to make a complete system. Ductwork, plenums and wired controller are sold separately.

Specifications
Compact and lightweight design
With a low weight of just 21 kg, this ventilation unit can be installed quickly and safely by a single installer. Its space-saving footprint makes the DucoBox Energy Comfort perfectly suited for small plant rooms and confined technical areas.
Software-controlled left/right configuration
The unit is designed for maximum installation flexibility. Left- or right-hand airflow orientation is adjusted entirely via software, eliminating the need for mechanical modifications. This is made possible by an innovative patented double bypass system.
Automatic calibration
Using constant pressure calibration technology, the AUTO calibration function reduces commissioning time by up to 50%. In real-world installations, this can translate into lower labour costs and faster system setup.
High energy efficiency
Advanced dynamic air filtration ensures consistently high heat recovery efficiency. When combined with optional intelligent demand control based on CO₂ and humidity sensors, the system delivers excellent indoor air quality while minimising energy consumption.
Smart copy function for fast commissioning
An integrated software-level copy feature allows installers to duplicate settings and parameters from one unit to another. This is especially valuable for multi-unit or repeated housing projects, ensuring consistent performance and significantly reducing setup time.
