Gardner Denver GDWS1100 DN150 water separator

Description Gardner Denver GDWS1100 DN150 water separator

Gardner Denver — a global leader in compressor equipment and compressed air treatment systems manufacturing — presents the GDWS Series (Condensate Separators), which is a critically important component of any professional pneumatic system. GDWS Series water separators provide reliable protection for expensive process equipment, serving as the first barrier against corrosion, premature wear, and pneumatic tool contamination.

Gardner Denver GDWS condensate separators are highly efficient cyclone separators that utilize the centrifugal separation principle to remove up to 99% of free water and liquid oil from the compressed air stream. This is not only a technical solution but also an environmentally responsible approach to condensate disposal, enabling enterprises to comply with strict environmental regulations.

Why is the GDWS Series Indispensable?

• Investment Protection: Prevents damage to expensive coalescing filters, dryers, and pneumatic tools
• First Line of Defense: Installed directly after the compressor or receiver
• Environmental Compliance: Simplifies condensate disposal process according to environmental standards
• Versatility: Compatible with all compressor types — reciprocating, screw, and rotary
•

Key advantages and model capabilities

✅ Reliable Equipment Protection

GDWS water separators provide effective protection of coalescing filters against liquid overload. By removing the bulk of condensate at the first stage, separators significantly extend the service life of filter elements and reduce replacement costs. Pneumatic tools, cylinders, valves, and automation receive dry, clean air.

✅ High Separation Efficiency

Thanks to centrifugal (cyclonic) technology, GDWS series water separators remove up to 99% of free water and liquid oil from the compressed air stream. This is achieved without using replaceable filter elements, substantially reducing operating costs.

✅ Low Operating Costs

The optimized cyclone chamber design ensures minimal pressure drop (less than 0.1 bar at rated capacity), directly affecting compressor station energy efficiency. Lower pressure drop means less energy consumed by the compressor.

✅ Wide Flow Range

The GDWS series covers the full spectrum of industrial needs — from 0.5 m³/min for small workshops to 200 m³/min for powerful production facilities. Every enterprise will find the optimal model for their requirements.

✅ Environmental Appropriateness

Effective oil-water separation at the first stage significantly simplifies subsequent condensate disposal. This helps enterprises comply with environmental legislation and avoid penalties for improper handling of industrial waste.

✅ Ease of Maintenance

GDWS water separator design provides easy access to the drain port and capability for automatic drain installation. The absence of replaceable filter elements minimizes the need for regular technical maintenance.

✅ Durability and Reliability

The use of cast aluminum (models 005-380) and welded structural steel (models 0400-2000) guarantees long service life even in aggressive industrial conditions.

Design description and operating principle (GDWS Technology)

Gardner Denver GDWS cyclone separators operate based on fundamental physical principles, using centrifugal force for effective separation of liquid particles from the gas stream.

Stage 1: Entry and flow rotation

Compressed air, saturated with water and oil droplets, enters the water separator through a tangential inlet port. Due to the special inlet channel geometry, the air stream acquires rotational motion, forming a stable vortex flow inside the cyclone chamber.

Stage 2: Centrifugal force action

As the air stream rotates, centrifugal force acts on liquid droplets, exceeding gravitational force by hundreds of times. This force throws heavier particles (water and oil) toward the outer wall of the separator housing, while cleaned air continues moving in the central zone.

Stage 3: Condensate collection in the quiet Zone

Liquid reaching the housing walls flows downward under gravity into a special quiet zone (calming chamber) located at the bottom of the separator. This zone is designed to prevent re-entrainment of separated liquid by the air stream.

Stage 4: Condensate drainage

Collected condensate is periodically removed through the drain port, which can be equipped with:

• Manual valve for periodic draining
• Float-type drain for automatic drainage
• Electronic timer valve for programmable discharge
• Intelligent drain with level sensor

Stage 5: Clean air exit

Cleaned air, freed from 99% of free moisture and oil, exits through the central outlet port and proceeds to subsequent treatment stages — dryers, coalescing filters, or directly to consumers.

Recommended installation location

For maximum efficiency, GDWS water separators are recommended for installation:

• Directly after the compressor — for primary removal of the main condensate mass
• After the air receiver — where additional moisture condensation occurs
• Before the dryer — to protect the dryer from liquid overload
• Before critical equipment — as an additional protective barrier
