Dräger RZ 7000 — portable tester for closed-circuit breathing apparatus (CCBA)
The Dräger RZ 7000 is a portable device for functional and leak tests of Dräger PSS BG4 plus and Dräger BG ProAir closed-circuit breathing apparatus (CCBA). Once switched on, it automatically zeroes the sensor and is ready to work, and a built-in hand pump generates both positive and negative pressure without any additional accessories. A compact, rugged IP54 housing and a lithium-ion battery (min. 24 h of operation) let you test equipment both in the ODO workshop and in the field.
Key features
- Fast and easy functional and leak tests for Dräger PSS BG4 plus and Dräger BG ProAir closed-circuit breathing apparatus (CCBA).
- Automatic sensor zeroing after switch-on — the device is ready to work immediately.
- A self-locking adapter ensures a secure connection to the apparatus throughout the test.
- Built-in hand pump (aluminium handle, stainless-steel shaft) — generates positive pressure immediately, and negative pressure after a single turn of the switch, with no additional switching needed.
- Five-position switch — selects the pump direction, flow measurement (automatic switch to the flow sensor) and rapid venting without disconnecting the apparatus.
- Backlit display shows the current pressure as well as the stored start and end values of the test; during the leak test a timer counts down the remaining time and calculates the pressure difference.
- Portable, rugged housing rated IP54 (with the cover closed), resistant to dust and splashing water.
- Lithium-ion battery — min. 24 h of operation without external power, configurable auto-shutdown, and can run while charging.
- Optional Dräger Protector Software documents the results and automatically tracks the dates of subsequent tests, with reports printed immediately or later.
- An optional test head extends testing to full-face masks with an RP connector.

Frequently asked questions (FAQ)
What breathing apparatus does the RZ 7000 test?
The RZ 7000 is used for functional and leak tests of Dräger PSS BG4 plus and Dräger BG ProAir closed-circuit breathing apparatus (CCBA). With the optional test head it can also test full-face masks with an RP connector.
Can the device be used outside the workshop?
Yes — it is a portable device in a compact, rugged IP54-rated housing, powered by a lithium-ion battery sufficient for min. 24 h of operation without external power; it can also run while charging.
How often does the RZ 7000 need to be calibrated?
The standard calibration interval is 24 months, subject to applicable national regulations.
Can the test results be documented?
Yes — the optional Dräger Protector Software saves the test results and automatically tracks the dates of subsequent tests; reports can be printed immediately or generated later.
