Changes to Valve Plate Assemblies for AC1 and AC2 Direct Drive compressor assemblies.
AC1 assemblies on F280, E150, C270, B230X-BOAT and previous single head, direct drive models.
AC2 assemblies on F390, E250, C390, CTD390, B340X-BOAT and previous dual head, direct drive models.
The following changes have been made to
Valve Plate Assemblies
for Brownie’s Third Lung direct-drive compressor
assemblies produced since June, 2005, beginning with serial number 12039.
1. Increased diameter of 4 port
holes
2. Removed material around the
outflow side of the port hole
3. Valve restraint material is now
aluminum, changed from high
temperature plastic
4. Changed flapper valve design
(see below)
These changes are designed to increase
airflow and provide greater service life of
the valve components.
The new flapper valves and restraints
are NOT backward compatible with the
previous valve plate design.
Compressors requiring service to replace
flapper valves and/or restraints will be
required to also replace the valve plate to
accommodate the new parts.
For your convenience, we have produced
a single part number for a preassembled
valve plate assembly (including the valve
plate, flapper valves, valve restraints,
screws, round o-ring, square o-ring),
AC-VPA, $55.00 each.
