Blower Sizing
The number of holes in the seats and
floor of the spa can be used to
determine the size of the air blower
that will be required for your
application. See Chart 1 for
recommended blower size based on
the number and size of holes.
Water Jet
Applications
The blower can be used to boost the
output of hydrotherapy jets. A venturi
fitting is normally incorporated into
the jet design. The purpose of the
fitting is to allow air to mix with the
water in the jet. The venturi fittings
can be connected together and then
pressurized with air from the blower to
greatly increase the jet action.

Applications
It is important to select a water pump
that will supply sufficient flow to the
jets. Consult with the jet manufacturer
for assistance in selecting a pump or
pumps that will accommodate the
number of jets desired in the spa.
Improper sizing can cause overheating
of the pump and blower.
Choose the correct size blower based
on the number of water jets in your
spa (see Chart 1). See the chart below.
Refer to the installation guidelines for
additional details.

Winterizing
The blower is designed for outdoor
use. There are no special off-season
requirements for the blower. In some
spa systems it is possible to protect
discharge lines from freezing by
operating the blower for several
minutes with the spa drained. The
airflow can be used to purge water
from the air lines.
