Robertshaw BP Series BYPASS ZONE DAMPERS - Manual

An ISO 9001 – 2000 Certified Company
Product Description
Robertshaw bypass non-electric zone dampers are
Simply the Right Choice™ to maintain proper airflow
and static pressure throughout the HVAC system.
A bypass system should incorporate bypass dampers
and a static pressure control device. We offer
non-electric barometric pressure dampers that are
self-regulating and field adjustable. They maintain
proper static pressure in the system without requiring
sensors or wiring. Robertshaw bypass dampers are
compatible with forced air and constant volume zone
systems requiring bypass air to maintain proper
static pressure.
Our bypass dampers can be mounted vertically or
horizontally due to unique static pressure with the
weight on either side for installation and adjustment
convenience. They are available in two sizes and can
be used with HVAC equipment with capacities of up
to five tons of cooling. All shells are constructed of
rolled galvanized steel with stiffening ribs to maintain
rigidity. A single steel offset blade is attached to a
one-piece steel shaft connected with nylon bearings
for smooth operation.

When Zoning Should Be Used
Robertshaw Zone Control Systems are compatible with
forced air heating and cooling systems, and they are ideal
for homes and building that exceed 2,500 square feet.
Zoning systems help overcome many of the heating and
cooling problems associated with spacious living and
working area, as well as contemporary architectural
features. You should consider zoning if your project is a
multiple-level home or building, a rambling structure like
ranch-style housing or schools, and has:
– Large glass windows susceptible to sunlight that varies
internal temperatures at different times of the day.
– Wings or additions extending from the main area.
– Vaulted ceilings, skylights, atriums or solariums.
– Finished attic, basement or room over the garage.
– Concrete slab flooring.
