SpacePak makes it possible to install central heating and cooling in any home or small business; regardless of structure design, age, size or type of construction. SpacePak is an air distribution system which uses a principle known as aspiration - as the air stream enters the room, it creates a gentle mixing of air in the room to provide thorough, comfortable draft-free air circulation. SpacePak eliminates stratification with a minimum floor-to-ceiling temperature difference.

SpacePak At-A-Glance

Cool, Evenly Distributed Air

The basic difference between SpacePak and other air conditioning systems is the way SpacePak actively circulates air within the room and throughout the structure's entire living/working space. Circulating the air more effectively is what makes a home with SpacePak central air so uniformly comfortable: no cold or warm spots, no drafts, and up to 30% more humidity removed.

Conventional central air systems merely drop cold air in at the ceiling; the distribution of cool air is haphazard, leading to over-cooling in some spots or drafts in others.

Window air conditioner units or mini-splits require noisy fans within the living space to blow the air around, and there is no overall circulation of the home's air.

Small, Flexible Tubing Instead of Sheet Metal Ductwork

A central heating or cooling system designed to actively circulate air can use smaller ducts than conventional systems; 2 inch mini duct insulated supply tubing keeps the air moving consistently—like pouring water from a pitcher. This smaller duct allows SpacePak to use flexible tubing to distribute the air instead of bulky sheet metal ductwork.

This tubing is seamless, so it doesn't waste energy through leaks like sheet metal. And it's flexible, so passages have no corners to accumulate dust, pollen, or mold. The tubing's narrow diameter allows it to be placed in the spaces behind walls, floors, and ceilings: it can be installed with virtually no disruption to livable space, nor to interior architectural features.

Central Air Built Around the Space You Have... or Want

SpacePak can be installed into either new construction or an existing structure. Either way, the simplicity of SpacePak's sized-to-fit tubular ducts requires just a fraction of the installation time and cost associated with having sheet metal ductwork fabricated and installed. No other company has more experience designing and building central air systems with the flexibility to fit into virtually any building. SpacePak is ideal for:

• historic buildings
• buildings without existing ductwork
• buildings that utilize radiant heat systems
• open floor plans
• log homes/cabins
• brownstones or row houses
• lofts
• additions
• modular homes

The Basics of a SpacePak Central Air System

While every installation is configured specially to the individual home's unique requirements, fundamentally the SpacePak system consists of the following components as labeled in the diagram below. Each one is briefly described below.

1. Outlets
2. Sound Attenuators
3. Kwik Connects
4. Flexible Ducts
5. Plenum
6. Fan Coil Unit
7. Return Air Duct
8. Return Air Box/PurePak Air Cleaner (optional)

1. Outlets: How the conditioned air enters the living space. These 5" diameter outlets (the size of a music CD; much smaller than conventional register grilles) can be placed in the ceiling, wall, or floor.
2. Sound Attenuators: Short lengths of flexible, baffled tubing. These tubes greatly reduce the audible sounds produced in the air movement process.
3. Kwik Connects: A no-tools-required system that quickly and easily joins the flexible ducts to sound attenuators and the plenum. Kwik Connects virtually eliminate leakage, improving efficiency, and greatly reduce install time.
4. Flexible Supply Tubing: These flexible, narrow, tubular ducts enable SpacePak to bring central air throughout the house within the normal space between walls, ceilings, or floors: no extensive renovation work. The number of ducts would be based on the size of the fan coil unit.
5. Plenum: Carries air to the different ducts which distribute it throughout the house. The plenum fits within the attic, basement, or crawl space where the fan coil unit is installed.
6. Fan Coil Unit: The fan distributes air through the plenum; the coils cool (or heat and cool) the air, depending on individual needs and system configuration. Connects to external condenser for cooling; SpacePak is compatible with most condenser brands.
7. Return Duct: The central heating or cooling system contains a blower that gets its air supply through this duct. The air from a room will move towards the lower pressure of the return duct. The duct also contains the properties of sound attenuation and is insulated.
8. Return Air Box: This is the sheet metal box that mounts directly to the return air grill. This allows the mating of the return duct to the grill.
   
   PurePak Air Cleaner (optional): A patented design that replaces the standard return air box. While 4–6" pleated filters are not effective at removing contaminants smaller than three microns (such as bacteria, auto exhaust, cooking smoke, dust, or paint pigments), PurePak captures contaminants as small as 0.3 microns with 97% effectiveness.
