Improve indoor air quality of your facility with Greenoz Exhaust Air Units – engineered for contaminated air extraction and optional filtration across industrial, commercial and healthcare environments. Our smart ventilation systems come with multi-stage filtration options, perfect for manufacturing facilities, shopping malls, office buildings, etc., requiring superior air quality control.
Indusrial & commercial buildings face mounting challenges in maintaining healthy indoor environments while managing energy costs effectively. Poor exhaust ventilation leads to contaminated air, odor buildup, and compromised occupant health. Â
Traditional exhaust systems often lack proper filtration and they send pollutants directly into the external environment without air treatment.Â
Our Solution: Greenoz Exhaust Air Units provide intelligent air extraction with optional multi-stage filtration, ensuring clean indoor environments while meeting environmental compliance requirements. Our energy-efficient design reduces operational costs while maintaining superior air quality standards.Â
Electronically commutated (EC) motors provide variable speed control with superior energy efficiency compared to traditional AC motors. These advanced motors automatically adjust to system demands, reducing power consumption while maintaining optimal airflow performance. This is available as option.
Variable frequency drive (VFD) systems offer precise airflow control for applications requiring specific ventilation rates. VFD technology can be integrated with building management systems (BMS) for automated operation based on occupancy, air quality sensors, or time schedules.
Dynamically balanced centrifugal fans mount on vibration-absorbing platforms, ensuring quiet operation suitable for noise-sensitive environments. It also helps to extend equipment life while maintaining consistent performance.
Choose from galvanized steel construction for standard applications or stainless steel for corrosive indoor environments. All construction options include powder coating or pre-coating finishes for maximum durability and aesthetic appeal.
Single skin construction provides cost-effective solutions for general commercial applications. Double skin configurations with extruded aluminum framework offer superior thermal performance and acoustic insulation for demanding environments.Â

Workshops, assembly lines, and industrial processes generate airborne contaminants requiring effective removal. Our robust construction handles demanding industrial environments while maintaining consistent performance.

Hospitals, isolation rooms, and pharmaceutical cleanrooms demand precise air quality control with contamination prevention. Optional fine filtration and carbon filters ensure compliance with healthcare air quality standards.

Office spaces, co-working facilities, and commercial lobbies require reliable exhaust ventilation maintaining comfortable environments while supporting productivity. Greenoz Exhaust Air Units handle standard office air quality requirements with energy-efficient operation.
Hinged or removable access panels provide easy maintenance access without system shutdown. Strategic component placement minimizes service time while ensuring all major components remain accessible for inspection and replacement.
Heavy-duty steel or aluminum base frames provide stable mounting with integrated vibration isolation. This design ensures proper system alignment while reducing vibration transmission to building structures.
High-density PUF insulation ranging from 25mm to 50mm thickness provides both thermal and acoustic performance.
Our engineering team analyzes your specific air quality requirements, building constraints, and operational needs to configure optimal system performance. Custom capacity calculations ensure proper sizing for effective contaminant removal.
Complete project management includes design, supply, testing, and commissioning services. Our Greater Noida facility supports nationwide project delivery with professional installation teams and technical support.
Modern exhaust air units can be integrated with building automation systems, enabling automated control based on occupancy schedules, air quality monitoring, or energy management programs. This integration optimizes performance while reducing operational costs.
Energy-efficient fan technology combined with smart controls reduces overall power consumption, supporting sustainability goals and green building certifications. Our systems contribute to LEED and other environmental rating systems.
Durable construction materials and quality components ensure extended equipment life with minimal maintenance requirements. This design approach reduces replacement costs while maintaining consistent performance throughout the equipment lifecycle.Â
G4 pre-filters capture coarse dust and particles, suitable for general commercial applications. F7 filters remove finer particles for healthcare environments, while F9 filters provide highest efficiency for pharmaceutical cleanrooms and sensitive applications requiring superior air quality.Â
EC motors provide variable speed control with 20-30% energy savings compared to standard AC motors. They offer precise airflow control, quieter operation, and longer service life, making them ideal for continuous-duty commercial applications.Â
G4 pre-filters typically require monthly inspection with quarterly replacement depending on air quality. Fine filters need replacement every 6-12 months, while carbon filters require annual replacement. Access panels enable quick filter changes without system shutdown.Â
Yes, our units support standard BMS communication protocols including 0-10V, 4-20mA, and digital interfaces. Integration enables automated operation based on occupancy, air quality sensors, or energy management schedules.Â
Commercial kitchens, laboratories, pharmaceutical facilities, and industrial processes generating chemical odors or VOCs benefit from carbon filtration. This option ensures both indoor air quality and environmental compliance for exhaust air.Â
Modular design enables flexible installation in various building configurations while supporting future capacity increases. Single or double skin options accommodate different performance requirements and budget considerations without compromising quality.
