MSD Research, Inc., an
innovator of HVAC products announced the launch of its
ALL-ACCESS Condensate Cleanout Device.
Model AA1 device installs easily into ¾” or 1” PVC drain lines in
either the horizontal or vertical position. Once installed, the
technician will never need to cut the drain line again to service
The ALL-ACCESS device allows the drain line to be cleared by
attaching a nitrogen hose to the top fitting and clearing the drain
line downstream from the unit. The flapper assembly inside the
device automatically closes to seal off the drain leading back into
the unit. Once the nitrogen pressure is removed the device remains
completely open and permits the full flow of condensate.
The device also protects the drain
line from being over pressurized by releasing air through the top
cover if too much pressure is sensed; it is recommended that no more
than 30 psi be used to clear a line.
The flapper holder assembly inside the device can be easily removed
allowing the technician to use the included adaptor to vacuum or
blow out the drain line in either direction using any method they
continues below ↓
By removing the
flapper holder assembly the technician can easily add drain line
desired. The top cover of the device can be removed if
necessary and the latch can be easily operated in tight spaces.
For the rare case of two air handlers tied into one drain line,
the AA1 comes with a flapper closer tool, which when installed
into the top cover keeps the flapper closed and turns the device
into a shutoff valve allowing the tech to clear the other units
There is also an inexpensive insulation for the device sold
separately for installing in
unconditioned spaces such as garages & attics.
The AA1-INS fits the
device perfectly making it easy to install and also creates a better
appearance. This device will be available to the wholesale
trade this August.
We believe that this product will help HVAC companies save time and
money and make drain line service a breeze.
