Medium Static Pressure Duct VRF System
CE Certified Gold Fin Anti-Corrosion Commercial HVAC - The Self-Calibrating 160 Pa Workhorse That Eliminates Commissioning Guesswork
Product Overview
299mm Slim Chassis, Three-Orientation Mounting, and a Digital Motor That Reads the Duct Network and Adjusts Itself
Incorrect static-pressure calibration is the primary cause of field under-performance in ducted installations. The Midea V8 Medium Static Pressure Duct eliminates this issue through a self-adapting digital fan motor: an onboard drive chip continuously measures external static pressure between 10 and 160 Pa and automatically adjusts motor output to match—eliminating DIP switches, manometer readings, and commissioning guesswork. Installers simply connect the ductwork, power up, and the unit handles the rest.
With a 299 mm body thickness, the chassis fits easily into standard plenum depths. Three installation orientations accommodate diverse ceiling layouts and duct routing patterns without requiring specialized models. For projects demanding superior air quality—healthcare clinics, laboratories, cleanrooms—the optional medical-grade HEPA filter module captures 99%+ of particles at 0.5 microns, transforming a comfort-cooling unit into a comprehensive air-treatment platform.
Operating within the V8 heat pump VRF architecture, this duct system provides both cooling and heating via reverse-cycle operation for year-round climate control. When paired with a heat recovery outdoor unit, it enables simultaneous heating and cooling across different zones—an energy recovery system that maximizes building efficiency while maintaining individual zone temperature control.
Core Features
160 Pa Static-Pressure Envelope
Sufficient external static pressure to handle typical commercial duct networks—multiple elbows, standard filter banks, and moderate diffuser arrays—without equipment overspecification. This capacity class covers the majority of real-world installations.
299 mm Uniform Chassis Depth
Every capacity model maintains the same 299 mm envelope, allowing ceiling plenum framing to be standardized floor-to-floor without capacity-dependent adjustments—significantly simplifying design coordination for mixed-use towers.
Three-Orientation Installation Flexibility
Accepts horizontal, vertical-down, and angled duct connections across three distinct port configurations—adapting to plenum layouts, beam obstructions, and architectural constraints without custom transition fittings.
Self-Adapting Digital Motor (10-160 Pa Range)
Embedded drive chip eliminates static-pressure calibration entirely. The motor autonomously senses the installed duct network's resistance profile and tunes its output in real time from 10 Pa to 160 Pa.
Medical-Grade HEPA Option (99%+ @ 0.5 μm)
For environments requiring airborne particle control, the optional HEPA module captures 99% or more of sub-micron particulates—elevating the unit from comfort appliance to genuine air-quality intervention device.
1,200 mm Pumped Drainage with Anomaly Signaling
Standard high-lift drainage includes digital fault-detection capability: pre-emptive alerts on RPM deviation or flow reduction protect building fabric before water damage occurs.
Half-Degree Setpoint Granularity
0.5°C / 1°C adjustment resolution provides facility engineers with precise command over zone conditions, enabling aggressive energy optimization without occupant callbacks.
