Shand & Jurs 97100 Manual Drip Trap

Rotating the disc first closes the gas inlet to the drain passage, then opens the drain. The gas path is always sealed during drainage, so no methane escapes to atmosphere and no air enters the piping system. This sequenced operation is the core safety feature of the 97100 and the reason it is appropriate for confined or occupied gas-handling locations.

Size the reservoir against the expected condensate accumulation rate and the planned inspection interval. Wet digester gas and landfill gas at longer intervals typically call for the 6-quart chamber; drier service or shorter rounds are well matched to the 3-quart chamber. Both are rated for 5 or 25 PSIG service and use the same 1-inch NPT connections.

The 97100 is manually actuated for attended sites where operators drain condensate during routine inspection rounds. The 97100E uses an electric actuator that can be timed, remotely triggered, or integrated into SCADA, and is the appropriate choice where drainage must occur on schedule or command without on-site personnel.

Use the 97101 High-Pressure Manual Drip Trap where the piping operates above the 25 PSIG envelope of the 97100. The 97101 is rated for service up to 100 PSIG on pressurized biogas, landfill gas, and vapor recovery headers. Below that envelope, the 97100 is the correct low-pressure device.

The 97100 is offered in aluminum or 316 stainless steel body construction, with stainless internal components and a choice of NBR or CR seal materials. An anodized aluminum disc/cover option is available for outdoor installations. Material selection should be matched to the gas composition and the presence of moisture or H₂S.

An optional insulation jacket is available to reduce the risk of freezing in cold-weather installations; a maintained heat source is required under the jacket. Use it on outdoor drip legs and exposed piping where ambient conditions would otherwise freeze accumulated condensate and block drainage.
