1 Safety Warnings
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not
come into contact with each other or any other moving part when in use. The parts should never be
subject to impact or mechanical strain.
Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.

2 Concept
The Swallow is an air cleaner designed for the removal of particulates and gaseous contaminants and
is typically suspended above the laser process workspace.
It is designed specifically for applications that include areas having high load particulate
concentrations such as laser welding where direct source capture may be difficult.
Laser fume absorbent canisters are also an optional stage of filtration to control odours and gases.
The 4000 cfm unit (6800m3/hr) accepts multiple stages of air filtration where the user can select
from a variety of particulate or gaseous/chemical filtration depending on the laser process.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.

2.2 System Description
The air cleaner is a self-contained unit with a fan, a pre-filter section, final filter section, (a HEPA
filter section,) and LED indicator lights to identify power on and filter change time. These indicator
lights are shown below.
The “Power On” indicator light illuminates as soon as power is energized to the system. The red
“Change Filter” indicator light illuminates once the pressure drop of the filters has exceeded the
recommended pressure. This indicates the filters are “dirty” and need to be replaced with new
filters.
The unit enclosure is constructed from 16-gauge powder-coated steel. The pre-filter and final filter
access is from the air intake end of the unit and includes an integral filter holding frame that enables
filters to be installed without using fasteners.
The unit accommodates a 2-inch or 4-inch prefilter. The second stage accommodates a specific
HVAC air filter. The third stage includes a HEPA filter holding frame for the HEPA air filter.
The fan is positioned at the air exit side of the unit and has a rated capacity of up to 4000 cfm
(6800m3/hr) with air filters installed.
An air supply register with adjustable directional louvers is built into the air exit side of the unit.
Main Features
The unit has a full-size air intake that draws fumes and other contaminants from the room. This air
is then filtered through each stage and re-circulated back into the conditioned space.
Typical Air changes per hour
Lasermet’s standard cabin measures 25’3” x 16’5” x 11’6” or 8 x 5 x 3.5m which is 140m3. For this
size of cabin, the Swallow Fume Extraction System will provide 50 air-changes per hour.

Swallow Instruction Manual
CEB00XXX-53-000 Page 6 of 12 Issue 2 30 January 2020
Internal air filter holding assemblies include gaskets which prevent air bypass and ensure that all of
the air is being treated by the system. Primary and secondary air filters are installed from this end of
the unit. Installation of replacement filters does not require tools or fasteners.
Filter options: Air filters can be selected specific to the volume and type of contaminant concerned.
The options include prefiltration, a secondary or final filter, and/or a HEPA or absorbent filter(s) at
the final stage.
The 4000 cfm (6800m3/hr) rated unit has a fan that provides a uniform airflow at sustainable noise
levels.
Adjustable directional louvers return the filtered air into the working space.
LED lights show when the unit is ON and the particulate air filter pressure drop (and unit operation).

3.1 Filter Installation
Warning: Do not install or replace filters with the system operating. Do not operate without the
proper filters installed.
The system is designed to accommodate up to (2) stages of filtration. Filters are installed in the inlet
FastFrame holding frame.
Bag filters, up to 30” depth, are the primary filtration with the optional addition of a 2” or 4”
prefilter in front of the primary filter, if required.
Primary Filter Installation
1. Justify the filter’s bottom edge to the back of the holding frame, allowing the filter to rest on
the compression tabs.
2. While pressing down on the filter, compress the tabs and rock filter forward into place.
3. Push and seat the filter against the gasket seal.

Swallow Instruction Manual
CEB00XXX-53-000 Page 8 of 12 Issue 2 30 January 2020
Pre-filter Installation (Optional)
Only use 2” or 4” depth cardboard frame prefilters.
1. Use the same method as previously described to install prefilter in front of primary filter.
2. Push and seat the filter against the primary filter. (Note: minor prefilter frame deflection is
expected.)
4 Wiring
The system is completely factory wired to a junction box located on the top panel.
See system label attached to top of system beside the junction box and apply correct inlet power
(see wiring diagrams on following pages).
Follow local electrical codes for inlet power connection.
Once local power is energized the Swallow Fume Extraction System will power on.
The green “Power on” indication light will illuminate to indicate power is applied.

5 Operation
Quick Start-Up
 Install filters into inlet holding frames and secure all doors.
 Connect inlet power and energize system. Green light will illuminate indicating “Power On”
5.1 Maintenance
Proper maintenance of the Swallow Fume Extraction System is vital for proper operation. To
maintain optimum performance, it is necessary to replace filters when they are no longer as efficient
as required or when the pressure drop becomes too high.
To determine when media change-out is required, the system is equipped with a red “Change
Filters” indicator light. Follow these guidelines to ensure your system is in optimal operation.
1. Filters
The pressure drop across the filter exceeds the recommended change-out pressure drop or
system design pressure. The recommended “dirty” or change-out pressure drop will
illuminate the red “Change Filters” light.
Disconnect power and refer to the filter installation.
2. System
The system should be periodically inspected, and routine maintenance checks or other
planned surveillance should be conducted. Check each system for torn gasket, broken welds,
fan belts, or any other indication that the system’s ability to contain the process airstream
has been compromised.
When placing an order for replacement filters, provide Lasermet with the serial number and
part number. This information can be found on the system label on top of the housing next
to the inlet power junction box. Refer to contact information at the back of this manual.
