SPEEDAIRE

SPEEDAIRE 4GNL9 condensate separator 1950 cfm 3 in NPT

SKU CH-840P-RJGJM

Automatic condensate separator removes moisture from compressed air at up to 1950 cfm with 3 in NPT connections

  • Handles 1950 cfm maximum flow for high-demand compressed-air systems
  • Automatic drain removes moisture without manual intervention
  • Rated to 235 psi for demanding industrial pressure requirements
  • Aluminium body resists corrosion while weighing only 16 lb
  • Operates from 35 °F minimum temperature for cold-environment reliability

1950 CFM condensate separator for compressed air

This SPEEDAIRE 4GNL9 separator removes moisture from compressed-air lines rated up to 1950 cfm at 100 psi. It connects with 3-inch NPT inlet and outlet ports and operates at pressures up to 235 psi. The unit is built for industrial pneumatic installations that need continuous water removal.

Automatic drain and aluminum body simplify

An automatic drain expels collected condensate without manual intervention, reducing downtime on high-flow systems. The aluminum housing resists corrosion from compressed-air moisture. Included drain hardware means the separator is ready for installation without extra parts.

Temperature and pressure limits define safe

Minimum operating temperature is 35 degrees F, so the separator must be protected from freezing conditions. Maximum pressure of 235 psi sets the upper bound for system design. Flow capacity drops to 1300 cfm at the 100 psi reference point, so pipe sizing must account for actual line pressure.

Questions about this item

How often does the automatic drain on the 4GNL9 need service or replacement?

The automatic drain is built into the separator and operates without a user-service schedule; inspect it during routine compressor maintenance and clean or replace only if condensate stops discharging properly.

At what flow does the 4GNL9 reach its pressure-drop limit under continuous operation?

The unit is rated for a maximum flow of 1,950 cfm at 100 psi; sustained flow above that rating will increase pressure drop beyond the design limit.

How much heat does the 4GNL9 add to the air stream when running all day at full flow?

As a passive mechanical separator with no powered components, it adds no measurable heat; the compressed air temperature leaving the unit matches the inlet temperature.
