HI-Q - Model PSU-2-GN-R&WS Series -Outdoor Rated, Continuous Duty, Mobile Cart Air Sampling Systems
This extremely popular, outdoor rated continuous duty air sampling system is intended for secure outdoor ambient particulate and/or gaseous air sampling. The pump, control valve, and control panel are all hard mounted in a heavy gauge TIG welded aluminum, fully lockable, fan cooled, weather proof enclosure. The control panel houses the power switch, fuse protection, resettable electronic timer and either an analog or digital flow display. The telescoping sampling inlets are adjust-able in height to allow for breathing zone air sampling. HI-Q’s MCV-260 mechanical flow control valve maintains a constant flow ±5% of the operator pre-set flow rate (up to the maximum capacity of the pump). The PSU is available with either a ¼ or ¾ HP oilless rotary vane vacuum pump.
Digital Flow Display
Panel mounted NIST traceable digital flow meter, custom calibrated per ANSI/NCSL Z540-1-1994 using customer supplied filter media. The digital panel meter has a 15 point linearization table that relates differential pressure to flow, and is accurately compensated for filter loading. The digital panel meter displays instantaneous flow, minimum/maximum flow, and total volume of air sampled. The minimum, maximum and total sample volume are user resetable. The digital panel meter has optional plug in cards that allow DeviceNet, RS-232, RS-485 communications as well as analog signal output and relay outputs for alarms. To order complete with PSU see ordering information. To order separately as a retro-fit kit for existing PSU`s use PN: PSU-DIG.

PSU-GN:
180° Gooseneck Inlet. This gooseneck style inlet has a 180° bend such that the filter holder is positioned to face downward. The inlet is equipped with an industry standard 3/8 female quick disconnect.
GN-R&WS:
Stainless steel rain and weather shield used to protect the filter holder and collection media.
PSU-RHLB:
High Efficiency Particulate Inlet. This laboratory tested inlet has been designed to maximize particulate sampling efficiency in
all weather conditions and is lockable to maintain chain of custody of the filter media. Solid, o-ring sealed base, ensures air flow
path through omni-directional inlet. HI-Q’s new bayonet lock filter holder is included with this inlet and features a radial o-ring
vacuum seal that prevents leakage from the outside of the filter holder as well as an axial o-ring seal under the circumference
of the filter media to prevent sample blow-by. The filter holder’s three piece design eliminates filter media twist when opening
and closing. The filter holder is spring loaded to maintain constant filter compression for varying filter media thicknesses. The
bayonet lock design opens and closes with a 120° rotation.
PSU-RHLB-RV:
Same inlet as described above set up to accept Standard “RV” series holders.
MRV-PSU-057:
Original PSU Inlet. Inlet assembly accepts holders designed for, and implemented on, the original PSU and PSU-2 samplers. The MRV- PSU-057 features a Stainless Steel, ½ Swagelock®, Male Quick Disconnect inside the lockable aluminum box. The gooseneck & lock box combination also includes a ½ Stainless Steel Female Quick Disconnect & Bug Screen feature for positioning on the inlet of the filter holder. Filter holder sold separately.
PSU-2-RAINHAT:
Rainhat inlet designed for PSU-2 or MRV-0523CV- PSU Series Air Samplers. Rainhat Inlet includes one stainless steel ½” Female
Quick Disconnect fitting on outlet to match PSU-2- ILFH inlet.
PSU-FH-CAP:
PSU-FH Protective Filter Holder Cap.
PSU-FH:
The PSU-FH filter holder features a robust cam-lock that opens and closes with a 120° rotation. The PSU-FH has unique radial and axial o-ring seals. The radial seal ensures no leakage from outside the filter holder and the axial seal around the circumference of the filter media ensures that the sample stream cannot bypass the filter collection media. The two-piece inlet design is spring loaded to compensate for different thicknesses of filter media while maintaining the radial and axial seals. The spring-loaded inlet design also prevents filter media damaged due to rotation during opening and closing of the filter holder. The PSU-FH fits into the new integral Rain Hat/Lock Box (P/N: PSU-RHLB). Each filter holder includes one aluminum transport cap to cover the inlet of the holder and protect the filter media/sample during transport.
PSU-FH-TOOL:
By placing the lower portion of the PSU-FH filter holder over this tool and pressing down, the honeycomb filter support is pushed up 1/8” and raises the filter paper for easy removal.
PSU-FH-CALADAPT:
PSU-X-H Audit Adapter. Calibration adapter for PSU-FH filter holder. Adapter slips onto top of PSU-FH filter holder. Includes 1/2” SS MALE Q/D.
PSU-2-ILFH:
"L" shaped aluminum filter holder designed for PSU-2, PSU-3 or MRV-0523CV-PSU series Air Sampling lock boxes. Holds standard (Blue) plastic media cassettes.
