Precision Source-Capture Extraction
The BOFA 1UA1020045 stay-put arm with funnel is designed to capture dust, fumes, and airborne particulate at the point of generation, which is critical for effective extraction.
When correctly positioned, extraction arms like this significantly reduce airborne contamination and improve workplace air quality.
The included funnel nozzle helps focus airflow directly where it is needed, maximising capture efficiency.

Key Features & Benefits
Adjustable “Stay-Put” Positioning
The arm features BOFA’s “stay-put” design, allowing it to be easily positioned and then remain fixed in place during operation.
This provides:
-
Accurate positioning at the dust source
-
Consistent extraction performance
-
Easy adjustment for different tasks
-
Improved usability in workshop environments
The arm can be repositioned by loosening or tightening the joints, allowing flexibility without losing stability.
Funnel Nozzle for Targeted Capture
The arm is fitted with a funnel-shaped nozzle, designed to capture airborne dust over a focused area.
Typical benefits include:
-
Improved capture of fine particulate
-
Reduced spread of airborne dust
-
Better visibility of the work area
-
More efficient airflow direction
Funnel nozzles are particularly effective in bench-top and precision applications where dust is generated in a defined area.
ESD-Safe Construction
The arm is manufactured from carbon-loaded materials, giving it ESD (Electrostatic Discharge) properties.
This makes it suitable for use in:
-
Electronics manufacturing
-
PCB assembly
-
Static-sensitive environments
Installation Requirements
This arm is designed to be used with:
-
A table bracket with clamp (for mounting)
-
A flush seal system (for airflow connection)
-
A 50mm hose (for extraction airflow)
It cannot be connected directly to the extraction unit without these components.
Ideal Applications
The BOFA stay-put arm is widely used in:
-
Jewellery workshops
-
Dental laboratories
-
CNC routing and engraving
-
Electronics and PCB assembly
-
Precision engineering environments
It is ideal for bench-mounted, single-user extraction setups.
