1'' Single-Action Air Vent – Air Removal for Irrigation Networks

The 1" single-acting airlock is an essential accessory for any irrigation system that requires the effective removal of accumulated air from pipes. It is manufactured for use in fertigation and drip irrigation systems, and its main function is to evacuate air pockets that arise from various causes in the network: air ingress during emptying, water hammer, pressure loss, or irregular flow.
Its installation, using a 1" female thread, allows for simple and secure mounting on the main branch or at strategic points in the network. During the system's filling phase, the suction cup allows air to escape so that all drippers activate simultaneously, ensuring a uniform start of irrigation. Likewise, during the discharge phase, it facilitates controlled air entry into the pipes and prevents the suction of dirt-laden water.
This solution helps optimize the performance of irrigation systems, preventing malfunctions, minimizing component wear, and ensuring that water reaches each dripper at the appropriate pressure. It is a reliable option for both domestic garden installations and more complex networks in agriculture or horticulture.

Product Features:

• Efficiently eliminates air pockets: Installed on the irrigation branch, this suction cup allows the evacuation of air accumulated during filling, preventing water hammer, pressure loss, or irregular flow.

• Improves drip irrigation performance: By allowing all compensated drippers to start at the same time, it ensures even water distribution and optimal performance of the entire system.

• Protects the network from dirt suction: When the system is discharged, it facilitates the entry of air so that a vacuum or suction is not created that draws contaminating particles into the branch.

• Easy and durable installation: With 1'' female thread, it easily adapts to the corresponding pipe and allows minimal maintenance, ideal for both domestic and professional installations.

• Fertigation system compatibility: Designed for irrigation systems that integrate drip fertilization, it helps maintain proper working pressure and system efficiency, even under fertilizer load.

Frequently Asked Questions:

• What is the purpose of a single-acting suction cup in an irrigation system?
  It is used to evacuate air pockets trapped in the pipe during filling or emptying of the system, preventing water hammer, irregular flow, or the entry of dirt through suction.

• Where should this 1'' suction cup be installed on the irrigation network?
  It is recommended to install it at the highest point of the branch or in a section where air pockets can accumulate, as well as in the final section before emptying the system, to ensure its proper functioning.

• What happens if a suction cup is not installed on a drip net?
  Failure to do so may result in uneven drip start-up, loss of pressure, irregular flow rate, and, when draining, suction of dirt-laden water that can damage components or contaminate the system.

• Is this suction cup compatible with fertigation systems?
  Yes; it is specifically designed for fertigation systems combined with drip irrigation, helping to maintain stable pressure and uniform performance even when applying liquid fertilizer.

• How do I install and maintain the single-acting suction cup?
  It is screwed into the appropriate location on the pipe using a 1" female thread. Maintenance consists of periodically checking that the air-free valve is not clogged and that it opens correctly when the system is filled/emptyed.
