Art. FDA-0020E3/8 – Stainless steel 3/8”F humidifier drinker

Art. FDA-0020E3/8 - Stainless steel 3/8”F humidifier drinker for swine (wet/dry feeding)

Product description

The FDA-0020E3/8 automatic stainless steel 3/8" female humidifier drinker is designed for use inside feeders (wet/dry systems), ensuring a constant water supply directly during feed consumption.

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-0020E3/8 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

Water flow rate varies based on the available pressure along the water line.

For piglets and growing pigs, a flow rate between 0.6 and 1.0 L/min is recommended to achieve proper feed moistening without excess.

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.
