Air Knocker

Stainless Steel (Flange Type)

Suitable for food and pharmaceutical, petrol-chemical …etc, where corrosion resistance and hygiene is preferred

Typical Applications

Features

The impact force of the air knocker can be easily adjusted via unique valve mechanism (patented) by varying the compressed air supply.

The ability to adjust the impact force will enhances the air knocker capability to work on unforeseen circumstances such as changes of material characteristic due to the process.

*The blue part is the unique “umbrella type valve”

Capability to Operate Multiple Air Knockers With One Controller

Beside working as a standalone unit, the air knocker also has a relay piping feature (patented) which can link multiple air knockers in cascade connection and operate with an air knocker’s controller or a solenoid valve. This feature is extremely useful where several air knockers installed on a same silo/hopper or on the same pipe line and it could significantly reduce the control component costs.

Multiple Air Knockers operated in Cascade Connection

* RKVS15 type does not support the relay piping.

Easy and Cost Effective to Add On to Existing Hopper/Piping

In combination used with fully pneumatic operated controller (AOC-1B), the air knocker can be easily add on to the hopper, piping …etc. without electrical works! The AOC-1B controller can be actuated manually by a 3-way hand valve (In-built) or automatically by an external 3-way solenoid valve or pneumatic valve. The electrical/pneumatic signal to actuate the solenoid/pneumatic valve could be from the down stream equipment such as rotary valve, slide gate valve, butterfly valve…etc.

Mounted without welding (RKVS15 only)

The RKVS15 can be installed with a M10 bolt. Therefore, it can be installed on your idea such as installation with the dedicated stay bracket, with no knocker mounting stay provided on the container or with no soldering of container.

Air knocker's repair kit available

The repair kit consists of 4 replacement parts only and can be easily replaced within 10 minutes.

High Reliability and Durability

The stainless steel knocker series have durability supported by high design basis and have a simple structure, which provides almost maintenance-free performance and requires no additional spare parts. In long-term delivery record of this air stainless steel knocker series, customers have appreciated its maintenance-free performance with almost no failure
