Waveguide Dryer GD-301-19"-1-SNMP Series

Dry air for networks, cables and signals; waveguide dryer for telecom and radar installations

The Delair GD‑301‑19"‑1‑SNMP waveguide dehydrator is designed to supply controlled dry air for the protection of networks, cables, waveguides, and signal transmission systems. Moisture ingress in these systems can result in corrosion, signal attenuation, and reduced operational reliability. The GD‑301‑19‑1‑SNMP addresses these challenges by delivering continuous dehydration in a compact, energy‑efficient design.  Its integrated communication capabilities make it particularly suitable for modern network environments where remote monitoring and system visibility are essential.

Moisture Control for Signal Integrity

Waveguides and signal paths are highly sensitive to humidity, even at low moisture levels. Over time, moisture can degrade signal quality and damage internal surfaces. The GD‑301‑19"‑1‑SNMP is engineered to maintain dry internal conditions, reducing the risk of condensation and helping preserve signal performance. Accurate humidity control supports stable operation and extends the service life of protected infrastructure, particularly in continuously operating networks.

Dehydration Performance and Capacity

The GD‑301‑19"‑1‑SNMP delivers a dry air capacity greater than 300 l/h, making it suitable for small to medium waveguide and cable installations. This capacity supports continuous dehydration, ensuring that moisture is consistently removed even under changing ambient conditions. The unit’s performance is optimized to balance effective drying with low energy consumption, supporting efficient long‑term operation.

Compact Design and Installation Flexibility

Designed with a compact footprint, the GD‑301‑19"‑1‑SNMP can be installed in space‑restricted technical environments. Low noise and low vibration characteristics make it suitable for indoor installations, including network rooms and transmission facilities. Mounting brackets are included as standard, simplifying installation and ensuring secure integration into existing infrastructure.

SNMP Communication and Remote Monitoring

The GD‑301‑19"‑1‑SNMP features internet communication and a web interface, enabling remote access to operational information. SNMP functionality allows the dehydrator to be integrated into centralized network management systems, improving visibility and supporting proactive maintenance. This connectivity makes the unit well suited for distributed networks where on‑site access may be limited.

Each Delair® pressurizer of the GD 31 - GD 1101 range is produced with two heat-regenerated adsorbers, an air compressor, a pressure switch, a pressure relief valve and an electronic control print. The combination results in a pressurizer which is suitable for fully continuous and automatic operation.
