11VF12-1
air filter
Description
Air filtration with 11VF12-1
This compact filter is used in pneumatic lines where the working medium must be protected from dust and other small particles. It is intended for air and gaseous nitrogen, with the flow direction shown by the arrow on the housing. By removing contamination before it reaches control equipment, the filter helps keep the pneumatic circuit in a clean working condition. Its small format makes it suitable for installation where the filter is fitted directly into a line rather than used as a separate service module. In the Aviamisto catalogue, it belongs to the filters category.

Where the 11VF12-1 filter is used
Maintenance documentation places the filter in pressurization and air-conditioning equipment on An-24, An-26 and An-30 aircraft. It is also documented in the air-conditioning and hydraulic-reservoir pressurization systems of the Yak-42. This gives maintenance teams a clear system context, but the aircraft installation, fittings and routing should always be confirmed before a replacement is ordered.
Replacement element for 11VF12-1
The filter assembly uses the replaceable non-regenerable element 340.101. This element is a service part of the filter, not a substitute for the complete assembly. During maintenance, it is worth checking the condition of the seals and the cleanliness of the connection points at the same time. A filter element may have the same number across several filter assemblies, so the complete unit must still be identified by its own marking. When ordering a replacement, confirm the filter index, element, seals and available documentation together.
Pneumatic system connection
On the An-24, An-26 and An-30 installation, the 11VF12-1 works in the pneumatic line with the 2077 air-pressure regulator and 2176B outlet valves. The filter helps keep the air line clean before the medium reaches the regulator and downstream pressure-control equipment. Correct flow direction, secure connections and the absence of mechanical damage are important practical checks when the unit is installed or inspected. Before connecting a replacement filter, technicians normally compare the thread, mounting points and flow arrow with the removed assembly. This simple check is particularly useful where several similar filters are present in the same aircraft system.
Ordering the 11VF12-1
Please use the exact Part Number 11VF12-1 when sending a request. The common search variants are listed in Technical Details to help identify the same part, but they do not replace the exact designation on the product passport or housing. A clear photograph of the installed unit and its marking is useful when the application cannot be confirmed from the part number alone. If available, the removed filter, its passport and the aircraft maintenance record provide the most reliable basis for selecting the required configuration. To avoid a mismatch, confirm the aircraft type, system location, connection and mounting configuration, required condition and documentation set before purchase.
