Is the Sharpe 606A a desiccant dryer?

The cited manufacturer documents identify a 5-micron filter and pressure controls. They do not identify a desiccant or membrane stage or publish a pressure dew point.

Which flow rating applies?

Sharpe publishes 120 cfm for the filter and 50 cfm for the regulator. Use the limit for the outlet path that supplies the equipment.

Sharpe 606A Air Control Unit: Documented Selection Guide

The Sharpe 606A is a point-of-use air-control assembly with documented filtration and pressure-control functions. It is not documented as a water-vapor dryer. Select it only when a 5-micron filter and its outlet arrangement meet the actual contaminant and airflow requirements.

Sharpe 606A Air Control Unit

Air-control stations that need 5-micron filtration, pressure regulation, and separate regulated and filtered outlets.

A high-capacity filter-regulator whose documented scope is removal of water, oil, and contamination, without a documented water-vapor drying claim.

Strengths

Manufacturer specifies 120 cfm filter capacity and 50 cfm regulator capacity
Includes a regulator, inverted gauge, air cock, regulated outlet, and filtered main-line outlet
Uses the Model 606 filter and a replaceable 19930 filter element

Trade-offs

Its documented filtration rating is 5 microns
It is not documented as a desiccant dryer, membrane dryer, or water-vapor dryer
The current product page states 200 psi, while manual 310601F states a 160 psi maximum working pressure

Documented configuration#

Sharpe identifies the unit as part U06720. The published configuration includes a Model 606 filter, regulator, gauge, air cock, regulated outlet, and filtered main-line outlet.

The product page states a 120 cfm filter capacity and a 50 cfm regulator capacity. These figures describe different paths. Equipment supplied through the regulator must be evaluated against the regulator capacity.

Filtration scope#

Sharpe specifies 5-micron filtration and states that the unit removes water, oil, and contamination. The cited evidence does not define the water phase, publish separation efficiency, or state a pressure dew point. Do not infer bulk-liquid or water-vapor performance that the documentation does not give.

For persistent water, first check the aftercooler, receiver, drains, piping slope, and dryer loading. A point-of-use filter cannot correct every upstream cause.

Resolve the pressure conflict#

The cited product page states a 200 psi maximum operating pressure. The cited manual states 160 psi for the illustrated air-control units and identifies the 606A. Because this is a safety-relevant conflict, inspect the exact unit nameplate and obtain written manufacturer confirmation before use above 160 psi.

Installation and service checks#

Confirm the inlet and outlet connections against the current manual.
Size the regulated path from its documented capacity.
Provide safe isolation and depressurize before service.
Inspect and drain the bowl as required by the current instructions.
Use the documented service element and record the service date.
Keep the unit accessible for gauge, drain, and element checks.

Decision#

This unit is useful when its documented filter, regulator, and outlet functions match the application. It is not a substitute for a dryer when water-vapor control is required. Do not proceed until the exact unit’s pressure rating, required flow path, and service parts are confirmed.
