Why Combine HVAC and ColPro Filtration?
– ColPro requires significant increases in make-up air and typically
the facility HVAC systems can not handle the additional
cooling/heating loads.
– Standard HVAC systems are not designed for higher pressures.
Systems have significant leaks.
– Elimination of redundant components

Why Modular Construction?
– Uses pre-designed modules
– Reduces NRE engineering and design requirements
– Promotes Product Standardization
9 Maintenance and Repair Parts
9 Manual Creation and Support
9 Standard Monitor/Control
Equipment
9 Standard Integration
with Building Control Systems
9 Training
9 Testing and Certification
– Allows assembly in confined spaces (Mechanical Rooms, etc.)
Why Rapidly Deployable?
– Minimizes Impact on the Mission Critical Facility / Shelter
– Reduces Installation Cost
9 Requires only electrical power connection, remote signal
connections, and outlet duct connection
9 Versatile Placement (pad, ground, parking lot, trailer mount)
– Reduces Installation Schedule
9 Hardware can be installed in 24 – 48 hours
– Shipping Requirements
9 Sized to allow standard truck transport with no oversize limits
exceeded.
9 Allows 2 systems per truck

Schedule Impact (Future CBR System)
9 Survey – System specification, minimize facility/shelter investigation
9 Design – Reduce scope to system configuration options
9 Manufacturing
- Inventory long lead items (fan, housings, VFD, etc.)
- Eliminate long lead items (design features)
9 Procurement Strategy – Quantity buy options
9 Testing – Perform testing at the factory & minimize in-field testing
