VacReg 3500 L/min, Blue

Vacuum Regulator with Blue Cone, 3500 litres per minute

Vaccuum regulators are mechanisms used to control and maintain a milking system’s desired vacuum pressure. The function of the regulator is to keep the system vacuum at a preset level by responding to fluctuating air admissions into the system. They control pressure with inlet and outlet ports that let higher pressure air into the system as needed.

Our 3500 and 7000 regulators are servo-controlled high capacity vacuum regulators. The 3500 has a capacity of 3500 litres per minute at 50 kPa and operates effectively over the range 36 - 50 kPa (11 - 15" Hg). The 7000 has a capacity of 7000 litres per minute at 50 kPa and operates effectively over the range 36 - 50 kPa (11 - 15" Hg).

The 3500 and 7000 regulators are designed to conform with the latest ISO standards. They are designed to automatically maintain a steady vacuum in the milking machine in spite of varying vacuum usage. Due to the servo control and the absence of a weight, it is not essential for our regulators to be fitted vertically, as it is for weight and spring operated regulators

• The servo principal provides rapid response to changes in milking vacuum, resulting in less violent vacuum fluctuation
• Remote vacuum sensing away from the valve mechanism
• Consistent performance due to the spring being a component of the pilot valve and not the main valve assembly. Its travel is therefore less than on a spring operated regulator.
• Optional silencer (baffle) which is used to dampen sound travelling down the vacuum line
• All regulators are fitted with a paper cartridge air cleaner element for the pilot valve air supply
• Available for vacuum capacities up to 3500 Lt/min and 7000 Lt/min
• Available with a range of coloured cones (blue, grey, orange and green) or without the cone
• High stock levels carried, with swift and efficient delivery
• All parts are replaceable
• Fully Serviceable, (all spare & serviceable parts available from us)
• Manufactured from tough, lightweight modern plastics

​​​​​​​CLEANING
The frequency of cleaning will depend upon the cleanliness of the environment. However, the paper filter cartridge, the main valve seating and the air jet should be checked at least once a month.

All our vacuum regulators are fitted with a paper cartridge air cleaner element for the pilot valve air supply. The only indication that the cartridge filter needs replacing is a rise in the working vacuum level. If removing the filter significantly lowers the vacuum level, then the filter should be replaced. Should it be found that the filter is having to be changed frequently, then the environment dust level should be examined.
It is necessary to clean the main valve should it become dirty. A dirty main valve can affect the operation of the regulator. It is possible to wipe or brush the valve through the holes in the base when the regulator is unscrewed from the clean air supply moulding.
The valve can also be lightly sprayed with a small jet of water whilst the regulator is operating at working vacuum. The clean air supply moulding should be removed and the regulator screwed into the tee before this operation is performed.
