What is a 3AFM Air Flowmeter?

The 3AFM Air Flowmeter is a precision air flow measuring and regulating instrument used in thermal spray coating systems to control compressed air supplied to spray equipment.

Compressed air in thermal spraying is used for:

Spray gun cooling
Nozzle cooling
Substrate cooling
Curtain air
Nozzle face air
Pneumatic control systems
Coating material flow stabilization

Accurate air flow control is essential for achieving consistent thermal spray coating performance.

Applications of 3AFM Air Flowmeter

The 3AFM Air Flowmeter is widely used in:

Thermal spray coating systems
Flame spray equipment
Metallizing machines
Arc spray systems
Wire flame spray guns
Plasma spray systems
Surface engineering industries
Industrial coating plants

Key Features of 3AFM Air Flowmeter

Precision Air Flow Control

The built-in precision needle valve allows accurate adjustment of compressed air flow.

Dual Reading Scale

The flowmeter supports:

NLPM (Normal Liters Per Minute)
SCFM (Standard Cubic Feet per Minute)

Visual Flow Monitoring

The float indicator provides instant visual monitoring of air flow levels.

Adjustable Pointer System

A moveable and lockable pointer helps operators maintain desired air flow settings.

Industrial Construction

Designed for continuous industrial thermal spray operations.

How 3AFM Air Flowmeter Works

The 3AFM controls and measures compressed air flow through a calibrated transparent flow tube.

As compressed air passes through:

The float rises according to flow rate
Operators monitor flow using the scale
Needle valve adjusts airflow precisely

The flow reading is taken from the widest point at the top of the float.

Main Components of 3AFM Air Flowmeter

Flow Control Valve

Used to regulate air flow through the flowmeter.

Air Inlet Fitting

Connects regulated compressed air supply.

Air Outlet Fitting

Supplies controlled air to thermal spray equipment.

Float Indicator

Displays current air flow level.

Pointer Assembly

Provides visual reference for desired flow settings.

NLPM & SCFM Scales

Allow easy reading in both metric and imperial units.

Importance of Air Flow in Thermal Spray Coating

Controlled compressed air is critical for:

Stable spray pattern
Proper atomization
Better coating adhesion
Uniform coating thickness
Cooling efficiency
Reduced overspray
Improved coating consistency

Incorrect airflow can affect coating quality and spray performance.
