Optimizing Air Quality & Reducing Costs in Clean Rooms with ASPRA Systems (as HEPA)
Enhance Efficiency And Minimize Maintenance By Implementing ASPRA Induct Systems In Air Handling Units
Maintaining optimal air quality in clean rooms is essential, yet the conventional use of HEPA filters presents significant challenges. These filters, often requiring multi-stage filtration and frequent maintenance, lead to high energy consumption and substantial operational costs. The process of maintaining HEPA filters necessitates production stoppages and re-validation of the clean room, further escalating expenses and downtime.The ASPRA Induct system, implemented between the Air Handling Unit (AHU) and the HEPA filters, reduces maintenance frequency and downtime, offering a more efficient and cost-effective alternative while ensuring compliance with clean room standards.

3. Result
Reduced maintenance frequency and downtime, offering a more efficient and cost-effective alternative while ensuring compliance with clean room standards.
Highlights
Reduced HEPA maintenance frequency in clean rooms.
Lower costs from minimized production stoppages.
Energy savings due to reduced pressure drops.
Extended HEPA lifespan while meeting ISO standards.

Detailed Process
1. PROBLEM DESCRIPTION — Clean rooms use multi-stage filtration, with a HEPA 13 or 14 filter often installed in the plenum. These multiple stages generate high pressure drops, leading to increased energy consumption.
Maintaining HEPA filters inside clean rooms requires production stoppages for maintenance and re-validation, incurring major costs depending on the ISO class of the clean room.
The Solution
2. THE SOLUTION — To reduce the frequency of HEPA filter maintenance in the plenums and minimize the need to enter the clean room and stop production, the ASPRA Induct system is implemented between the Air Handling Unit (AHU) and the HEPA system.Alternatively, the ASPRA system can be integrated into the AHU.
The Result
3. THE RESULT — Significant costs reduction:- Extending the life time of the conventional HEPA (is replaced only to comply with ISO requirements)- Major costs savings on HEPA filters, production stop, validation of the clean room.- Major energy savings as the ASPRA does not clog and the HEPA stays clean.The ASPRA system captures all particles intended for the HEPA filter, rendering the HEPA filter redundant. The HEPA filter remains in place solely to comply with building codes for clean rooms. Once the traditional HEPA filter is no longer required, ASPRA serves as the perfect alternative.
