HVAC Equipment for Hospitals & Healthcare Facilities
Healthcare facilities demand a level of sanitation and reliability that only the highest quality environmental separation, ventilation and filtration equipment can provide.
Hospital HVAC equipment and climate control systems are required to remain energy efficient.Ā
This article explains typical challenges ventilating healthcare facilities, specifically hospitals and what HVAC equipment is available.
To achieve clean air, proper industrial ventilation equipment from a trusted source is needed. Biotechnology and pharmaceutical enterprises utilize industrial fans, blowers, and dust collection systems to contain potentially hazardous byproducts while controlling the indoor air quality.
Typical HVAC systems in biotech and pharmaceutical settings require rooms to be sealed and biotech air filters to remain at a high standard. Heavy duty ventilation fans that can ventilate sealed rooms, or clean rooms, while also filtering sub-microns. The pharmaceutical ventilation equipment that is able to accomplish this must also be efficient, yet produce low-noise and vibration-free.
R & D (Research & Development), pharmaceutical manufacturing or trial testing of drugs, each process carries unique demands for safe handling. With the potential corrosives, bio-hazards and filtration requirements – this creates a duty point that few manufacturers can satisfy.
Careful consideration must be given to the governing and regulation agencies mandating code compliance for environmental hygiene, safety, which includes noise, clean air and explosion suppression. Add all this together and you have a truly unique environment.
Air Curtains for Hospitals
Air Curtains and air doors are beneficial in hospitals for environmental separation. A significant concern for hospitals is keeping pathogens and pollutants isolated and even eliminated. Air curtains in health care facilities address these concerns as well as other indoor air quality (IAQ) issues.
Air curtains provide an invisible barrier to separate environments, while stabilizing pressure and temperature. They are able to work in tandem with other mechanical hvac equipment in hospitals.
Another added benefit of air curtains is they assist in preventing viruses from spreading (source), while killing bacteria and mold spores at the door. This helps improve indoor air quality of the space further.
When the door is open, occupants pass through a stream filled with carcinogen-free ionized air. When the door is closed, the motor goes into a power efficiency setting while purifying the indoor air in the space. If the area is unoccupied, the air curtain can be programmed to run at a powerful high speed, de-stratifying the air in the room and purifying it at optimum ion density.
Air Curtains Reduces & Eliminates:
- Odors
- Allergens
- VOCs
- And other particles

Exhaust Fans in Hospitals
Ventilation in hospitals is not complete without exhaust fans. The American Hospital Association recommends disinfectant exhaust fans. Disinfectant fans work to keep the area contaminantĀ and bacteria free.Ā
In the operating room, air flow should be directed in specific areas. Contaminated air is moved and tempered air replaces it.
Inline Duct Exhaust Fans
To help maintain airflow of particles such as viruses, bacteria and dust, hospitals often place ventilation equipment in air ducts. Air exchanges are used in order to vent stale air and move fresh air into a space.
For more ventilation inline duct fans may be needed. Square inline duct fans are available if space is limited.
Roof Exhaust Fans
A variety of roof mounted exhaust fans are available to suit a hospital’s needs. Typical rooftop fans include:
- Centrifugal downblast fan
- Mixed flow upblast fan
- Centrifugal upblast fan
- Axial upblast fan
- Centrifugal supply fan
- Hooded axial exhaust fan
- Hooded axial supply fan
- Hooded axial reversible fan
These roof exhaust fans are able to increase the amount of fresh air into specific sections of the hospital. Conversely, the exhaust fans limit the movement of contaminated air. The purpose is to improve IAQ while simultaneously lowering the risk of circulating airborne bacteria.

Hospital Grade HEPA Filters
HEPA filters are the standard filtration filters installed within HVAC systems that are used in hospitals, clinics, healthcare facilities and dentists offices.
Hospital grade filters use H13 filters which remove 99.9% of airborne particles down to 0.1 micrometers in diameter. These filters are MERV-A rated and able to capture dust, vapors, pollen and other tiny airborne particles that canāt be seen.
Supply Louvers, Exhaust Grilles & Dampers
The CDC recommends directional airflow to move air from a clean-to-less-clean direction (source). This is achieved by evaluating and repositioning the louvers, grilles and dampers as necessary. When the exhaust and supply points are located in a ceiling grid system itās more manageable to accomplish.
Ultraviolet Germicidal Irradiation (UVGI) in Hospitals (UVC Light)
UVGI in hospitals or UV lights are used to kill bacterial, viral and fungal organisms. UVGI is typically supplied in three system types:
- Upper Room
- Portable
- In-Duct
Upper room UVGI units are able to eliminate airborne pathogens, especially when the infection is localized. Portable UVC lights are attached to a mobile unit. The UV lights used in portable units are high-powered for an effective room disinfectant. In-duct UVGI uses mercury lamps to treat air in the centralized HVAC system as it circulates through the healthcare facility.
Ā
Typical configurations of UV-C lights are set downstream from the cooling unit in order to deal with the micro-organisms. In contrast, HEPA filters are placed upstream to filter out viral and airborne contaminants.

Dust Collectors for Pharmaceutical Manufacturing
If your laboratory or pharmaceutical manufacturing facility engages in any of the aforementioned operations then a dust collector is necessary. Implementing a dust collector in a pharmaceutical manufacturing facility that is dependable and durable is paramount to the operation’s success.
Tablet coating dust collectors are perfect for high-efficiency filtration. This prevents tablet pressing compounds to affect personnel while working in a pharmaceutical facility.
OSHA mandates laboratories and pharmaceutical facilities to meet IAQ standards. All dust collectors provided by AGET, A.C.T & Trion comply with OSHA mandates. With a wide variety of dust collectors from various manufacturers your biotech laboratory and pharmacy can rest assured the facility is implementing the appropriate pharmaceutical dust collector.
The best dust collection equipment for pharmaceutical manufacturing companies feature units that reduce energy costs by using low-pressure HEPA filters. They are also constructed with pressure-resistant and explosion protection steel. Dust collectors help reduce costs by recirculating the air with HEPA filters.
The quiet operation and bag-in/bag-out dust collector housing with filter change option is available to isolate personnel from hazardous material while replacing the filter.
Material Conveying - Pneumatic & Mechanical
Both mechanical and pneumatic conveying fans include free impellers made of steel plates or stainless steel radial blades. Radial blade fans and blowers are most commonly used for material conveying such as in the pharmaceutical manufacturing and other laboratory applications.
