Product Made In Japan
Manufacturer: KONAN
Model: ADF Series

An automatic drain has been fitted to the air filters. This separates and removes the drain from the pneumatic line, thus preventing trouble.

Operation

❶ If sufficient drain fluid, separated out by the filter, collects in the float case, the inner and outer floats rise under the buoyancy of the drain.

❷ The inner float pushes up the piston while the outer float presses the outer ring of the piston and the seal on the lower part of the upper lid. Thus, airflow between chambers A and B is shut off.

❸ As air is consumed in this condition,a pressure differential occurs between chambers A and B. If the differential rises above 10％, the piston rises further, and the bottom valve is opened, allowing drain fluid to discharge. After drainage, the pressures in chambers A and B equalizes, and the piston descends, closing the bottom valve.

❹ Therefore, if the air is consumed intermittently under the control of a solenoid valve, the air filter works well. Below an operating air pressure of 0.05MPa, the upward forces from the buoyancy of both floats automatically cause the piston to rise, the bottom valve to open, and the drain to be discharged, whether or not there is a pressure difference present between the chambers. Pressing the pushbutton for manual discharge opens the bottom valve and causes the drain to be discharged, regardless of the operating air pressure.

Operating Instructions

Installation

● Installation point
Install as far as possible from the air source and free of risk of impact.

● Bowl removal dimension
① Leave room so that the bowl can be removed and the filter element checked.
② Install the air filter and piping so that the drain port is located at the dead bottom.

Discharging drain fluid

● Drainage conditions
① When the pressure in the bowl falls 10% or more below the air supply pressure from the operation,of peripheral devices.
② When the air supply pressure is 0.05MPa and below.
③ When the pushbutton for manual discharge is pressed.
