The BAPI ZPS-ACC20 is a low profile “button” pressure pickup port smaller than a U.S. quarter in diameter, engineered to blend into its surroundings with minimal visual presence. It attaches to any clean, dry surface via the included adhesive ring for completely tool-free installation. The ABS plastic housing with integral 80 micron sintered stainless steel filter delivers reliable performance across a wide environmental range not available in standard plate-style ports.
Sub-Quarter Footprint
At 0.88 in [22.2 mm] diameter, the ZPS-ACC20 is the smallest BAPI pressure pickup option available—smaller and less obtrusive than any wall plate or Quantum enclosure-style port in the ZPS line.
Adhesive Mount — No Tools
Includes an adhesive ring for tool-free surface mounting. No fasteners, wall anchors, or penetrations are required for the port itself—route only the sensing tubing through the surface to the sensor.
Extended Environmental Range
Rated -40 to 185°F (-40 to 85°C) and 0–100% RH non-condensing, the ZPS-ACC20 is suitable for mechanical rooms, unheated spaces, and outdoor enclosures well outside the 32–122°F range of the steel plate models.

Frequently Asked Questions
Is a temperature sensor option available on the ZPS-ACC20?
No. Temperature sensor options are not available for the ZPS-ACC20 low profile model. For combined pressure pickup and temperature sensing at the same location, select the ZPS-ACC04 or ZPS-ACC04-60 Quantum enclosure models with the appropriate temperature sensor suffix.
Why does the ZPS-ACC20 have a wider temperature range than the wall and ceiling plate models?
The low profile button's ABS plastic construction and fully enclosed design allow operation from -40 to 185°F (-40 to 85°C), making it suitable for mechanical spaces, outdoor enclosures, and other environments outside the 32–122°F range of the stainless steel and galvanized plate ports.
How durable is the adhesive ring mount under normal operating conditions?
The adhesive ring provides reliable long-term mounting on clean, dry, non-porous surfaces under normal HVAC operating conditions. For installations subject to mechanical vibration, repeated contact, or repositioning requirements, contact BAPI for alternative mounting guidance.
