The major equipment by product type includes HVAC systems, high-efficiency particulate arrestance (HEPA) filters, and fan filter units.

HVAC systems are the largest contributor to the global cleanroom equipment market. The HVAC systems segment was valued at $470.1 million in 2015. The increasing need for energy-efficient solutions in the cleanroom market is fueling HVAC demand.

HEPA filters are the second largest contributor to the global cleanroom equipment market. The HEPA filters segment was valued at $273 million in 2015. All certified cleanrooms must use HEPA filters for air filtering. The point of entry needs to be evaluated with regard to the equipment, process, and/or personnel that the air will likely encounter. The location of the point of exit in the room ensures the ready exit of air without any entrained particles being deposited in critical areas. High entry and low return is still the most preferred airflow scheme in most cleanrooms, and software solutions are increasingly being used to visualize the flow pattern.

The fan filter unit segment was valued at $165.9 million in 2015. Fan filter units enable replacement of HEPA or ultra-low particulate air (ULPA) filters inside the cleanroom without having to shut down and breach the cleanroom seal. As downtime and recertification are time-consuming and costly, fan filter units are designed to allow access to filters in order to limit the downtime needed for regular maintenance. The filter modules contain gel-filled channels that seal against the module housing. From inside the room, sliding the easy-to-open clamps releases the filter for service or replacement. Once the new filter is lifted, the room becomes operational. However, in conventional filter units, filter replacement requires roof access or a complete shutdown of the cleanroom.
