TA471 Desiccator
SKU: TA471

TA471 Desiccator


The TA471 Desiccator combines our TA346 Humidity Indicator with a porous plastic desiccant cartridge. The increased size of the TA471 when compared to the TA366 desiccator allows for easier viewing of the humidity indicating card as well as additional desiccant capacity. Like the TA366 Desiccator the increased surface area provided by the porous plastic cartridge increases moisture adsorption rates when compared to a desiccator with a solid cartridge.

Various cartridge lengths from 1" up to 9" (or in some cases more) can be provided to meet specific adsorption or space requirements. Each inch of cartridge contains approximately 11 grams of desiccant. The condition of the desiccant is monitored by the humidity indicator card. Assemblies can be supplied with either silica gel or molecular sieve desiccant, and with a variety of different humidity indicator cards.

Maximum Internal Pressure: 10 psi

RFI/EMI Shielding is optional. Also available with our TA396 Humidity Indicator as a TA473.

This desiccator mounts through a 1.45" (37 mm) diameter hole or into a mounting flange, 658840.

Specify the type of desiccant, cartridge length (shown as nominal length "A" in the drawing below), and humidity indicator card in the part number. For example, TA471-MS4-123P is a TA471 desiccator with a 4"-long cartridge filled with molecular sieve and fitted with a 10%-20%-30% pie sector humidity indicator card; TA471-SG2.5-40 is a TA471 desiccator with a 2.5”-long cartridge filled with silica gel and fitted with a 40% humidity indicator card.

NOTE: This desiccator is not refillable. Replacement cartridges can be ordered by designating “RC”, desiccant type, and cartridge length. For instance, the replacement cartridges for the desiccators listed in the previous paragraph are TA471-RC-MS4 and TA471-RC-SG2.5.

Hex nut is standard.

The TA471 is appropriate for use on NEMA 1, 2, 3, 3R, 3S, 4, 5, 6, 12, 12K, and 13 enclosures, as well as I66/IP67 enclosures. This item may also be appropriate for use on other NEMA or IP enclosures, depending upon the application. Customized versions available upon request.
