Product Description
Midea VC Max DOAS Fresh Air System
Transform building air quality with continuous fresh air delivery for healthier tenants and improved property value.
Product Overview
Indoor air quality significantly impacts tenant satisfaction and retention. The Midea VC Max Dedicated Outdoor Air System (DOAS) addresses this by continuously delivering properly conditioned fresh outdoor air—pre-cooled, dehumidified, and filtered—to create clean, comfortable indoor environments.
With capacities ranging from 8 to 24 HP and airflow from 16,000 to 40,000 m³/h, the VC Max serves commercial spaces of all sizes. Integrated energy recovery reduces conditioning energy by 40-60%, making continuous fresh air ventilation economically sustainable while transforming indoor air quality into a competitive advantage.
Key Features
Immediate Tenant Satisfaction
Tenants notice improved air quality within minutes—lighter, clearer air that eliminates stuffiness and reduces complaints about headaches and drowsiness.
  • Occupants feel difference within minutes—air becomes lighter and more energizing
  • Eliminates stuffy, recycled-air feeling completely
  • Reduces headache and drowsiness complaints to zero
  • Improves tenant satisfaction scores measurably
  • Powerful leasing differentiator during property tours
Health Building Certification
Enables qualification for WELL, fitwel, and other health-focused building certifications by maintaining optimal indoor air conditions.
  • Maintains CO2 within 600-800 ppm per ASHRAE and WHO guidelines
  • Provides 45-55% relative humidity supply for optimal comfort
  • Multi-stage filtration removes particulates
  • Supports premium rental rates of 5-15% above non-certified properties
  • Appeals to corporate tenants with ESG commitments
Deep Dehumidification
Protects building structures and contents by controlling moisture levels and preventing mold growth and material damage.
  • Extracts moisture before outdoor air enters the building
  • Maintains indoor RH at 40-60% for comfort and preservation
  • Prevents mold growth, wood warping, and electronic corrosion
  • Reduces building maintenance costs and liability exposure
Energy Recovery
Makes fresh air ventilation economically viable with significant energy savings through advanced thermal exchange technology.
  • Integrated energy recovery reduces conditioning energy by 40-60%
  • EC fan motors use up to 60% less electricity than conventional AC motors
  • Variable-speed compressor matches output to ventilation demand
  • Economically sustainable fresh air delivery
Seamless Integration
Works with any existing HVAC system as a standalone air quality upgrade without replacing current equipment.
  • Partners with VRF, FCU, AHU, or other primary HVAC systems
  • Direct connection to existing duct distribution
  • Native BACnet and Modbus RTU for BMS coordination
  • Extends life of existing HVAC while improving air quality
Tenant Retention Strategy
Fresh air quality becomes a powerful differentiator that improves tenant satisfaction and reduces turnover costs.
  • Employees feel more alert with reduced afternoon fatigue
  • Prevents tenant turnover—investment recovery within 1-2 years
  • Reduces vacancy loss, leasing commissions, and improvement allowances
  • Attracts health-conscious corporate tenants
