Art. FDA-000020ETP - 1/2" automatic stainless steel adjustable humidifier drinker for swine feeders (eat/drink)

Product description

The FDA-000020ETP 1/2" automatic humidifier drinker is designed for use inside feeders (eat and drink systems), ensuring consistent water delivery directly during feed intake.

This solution improves feed intake, promotes animal hydration, and reduces waste, keeping the rearing area cleaner.

Made with robust and wear-resistant materials, it is ideal for pig farms requiring reliability, durability, and ease of management.

Installation heights and angle

The indicated heights are general guidelines.

The FDA-000020ETP drinker is designed to be installed inside feeders, so that the pig can activate it while eating.

For piglet rearing, we recommend using two installation heights or height adjusters to adapt the position to the animals' growth.

The inclination can be adjusted between 30° and 45°:

• Piglets (7–20 kg)

  • Height: 8–12 cm above feeder bottom
  • Angle: 30°–45°
  • Pressure: 0.5–1.5 bar
  • Flow rate: 0.5–0.8 L/min

  ---

  Weaners / Growers (20–40 kg)

  • Height: 12–18 cm
  • Angle: 35°–45°
  • Pressure: 1–2 bar
  • Flow rate: 0.7–1.0 L/min

  ---

  Finishers (40–80 kg)

  • Height: 18–25 cm
  • Angle: 40°–45°
  • Pressure: 1–2.5 bar
  • Flow rate: 0.8–1.2 L/min

  ---

  Fattening (80–120+ kg)

  • Height: 25–35 cm
  • Angle: 45° - 90°
  • Pressure: 1.5–3 bar
  • Flow rate: 1.0–1.5 L/min

Correct installation allows the water flow to be directed straight into the feed, reducing waste and improving feed efficiency.

Recommended water pressure

All drinkers work at both low and high pressure, with a maximum value of 4 bar (55 psi).

For piglet rearing, water pressure should not exceed 2 bar (28 psi).

In general, lower pressures promote:

• water savings

• less wear on seals and spring

• gentler water flow

• greater ease of use

• waste reduction

👉 We recommend using a pressure reducer in the presence of high or variable values.

Water flow rate

👉 (CLICK HERE) for the flow rate table

The flow rate of the 1/2" automatic nipple drinker varies based on the pressure in the water line.

For optimal system operation, a flow rate between 0.7 and 1.5 L/min is recommended to achieve correct feed moistening, reducing water waste and keeping the feeding area cleaner.

In the version with adjustable valve (model FDA-000020ETP), the flow rate can be set via the valve cap, allowing the flow to be adapted to the available pressure in the system.

Three adjustment levels are highlighted in the graph:

• Level 1 (2–9 bar) – green zone
  for high-pressure systems

• Level 2 (1–2 bar) – blue zone
  for intermediate pressures

• Level 3 (0–1 bar) – grey zone
  for low-pressure lines

The graph allows you to quickly identify the correct level to set on the cap to obtain a stable flow rate based on the available pressure.

With correct adjustment, the flow rate remains around 1.0 L/min, ensuring a constant, reliable flow suitable for different farming conditions.

The use of pressure reducers allows for centralized flow management, particularly useful during hot periods.

Water contamination

Contamination of water or pipes is one of the main causes of drinker malfunction.

The presence of impurities or sediment can compromise the correct operation of the system and reduce its lifespan.

👉 We recommend installing a filter on the water system to prevent these issues and ensure consistent performance.
