Baldwin BT310 Spin-On Filter
The Baldwin BT310 is a full-flow lube spin-on oil filter designed for HVAC control systems. It features an M20 x 1.5mm thread size and an overall height of 3-17/32 inches. The transparent housing allows visual inspection of the element condition during routine maintenance checks.
Suits Yale equipment requiring M20 threads
This filter fits Yale equipment specifying an M20 x 1.50 thread pitch and the listed dimensions. It is not intended for engines or hydraulic circuits using different thread standards, bypass pressures, or mounting configurations outside the stated specifications.
Includes 2 psid bypass and anti-drainback valves
The integrated 2 psid bypass valve maintains oil flow if the element becomes restricted during operation. The anti-drainback valve prevents dry starts by retaining oil in the filter after shutdown. No additional gaskets or installation hardware are mentioned in the supplied data.

Questions about this item
What thread size must the engine block have for the BT310 filter to seal properly?
The filter uses an M20 x 1.5mm thread, so the mounting boss must match that pitch and diameter.
Will the 18 micron rating and 2 psid bypass valve protect an older Yale engine that previously used a coarser filter?
Yes, the finer 18 micron media traps smaller particles while the bypass valve opens at 2 psid to maintain flow if the element loads up.
How can I confirm the anti-drainback valve is holding oil after the first start-up?
After shutting off a warm engine, wait a few minutes and check that the filter remains full of oil with no dry-start rattle on restart.
