SPEEDAIRE

SPEEDAIRE CDD-030 Desiccant Dryer 30 cfm 290 psi 5 in

SKU CH-W4GQ-WRZJ3

Removes moisture from compressed air to a -40 °F dew point at 30 cfm and 290 psi maximum pressure

  • ISO Class 2 dew point -40 °F delivers ultra-dry compressed air
  • 30 cfm maximum flow rate supports high-demand pneumatic tools
  • 290 psi maximum operating pressure handles heavy-duty industrial systems
  • 15 micron filter rating removes fine particulates for cleaner air
  • Aluminium body and bowl resist corrosion for longer service life

Desiccant Dryer for Compressed Air

The SPEEDAIRE CDD-030 removes moisture from compressed air systems at a maximum flow of 30 cfm. It delivers ISO Class 2 air quality with a dew point of -40 degrees F. The unit operates up to 290 psi and fits inline with 1/2 inch NPT connections. It is built for industrial and automotive shops needing dry air for tools and finishing.

Sustained Operation at Rated Pressure

At 100 psi the dryer maintains its full 30 cfm rating without pressure drop across the 15 micron filter. The 6.5 lb desiccant bowl provides continuous drying through extended shifts. Aluminum body and bowl construction resists corrosion under constant pressurisation. Minimum operating temperature of 35 degrees F ensures reliable performance in unheated spaces.

Upgrade from Basic Filtration

This dryer replaces simple particulate filters when moisture causes tool wear or paint defects. The jump is worth it if your application demands ISO Class 2 dew point rather than basic water separation. It does not suit systems requiring higher flow rates or integrated filtration packages. Buyers needing point-of-use drying for multiple stations should size accordingly.

Questions about this item

How much heat does the CDD-030 generate when running continuously at 30 cfm?

The dryer operates down to 35 Degrees F ambient and delivers a -40 Degrees F dew point without external heating, so heat output is minimal during continuous use.

What fittings and filtration must I already have to install this 1/2 in NPT dryer?

You need 1/2 in NPT piping on both inlet and outlet plus a separate pre-filter rated at 15 micron or finer, because no filter is included.

Will the 290 psi rating and 6.5 lb desiccant bowl work with my older 100 psi compressor?

Yes, the dryer handles up to 290 psi and is rated for 30 cfm at 100 psi, so it matches the older compressor’s pressure and flow directly.
