Legacy duct audits
Older duct runs can hide unused branches, leakage and abrupt changes that waste fan pressure.
Source capture, extraction ducting, dust collectors, fans, repairs and upgrades for fabrication, engineering, workshops and production plants in Germiston and nearby Gauteng industrial areas.
For Germiston sites, we do not assume an old extraction system needs total replacement. We first identify where performance is being lost—capture geometry, blocked or leaking ductwork, filter resistance, fan condition or unbalanced extensions.
Where useful infrastructure already exists, a targeted redesign can retain sound components while correcting the parts that restrict airflow or maintenance.
Germiston has long-established engineering, metalworking, fabrication, warehousing and manufacturing activity. Older premises can have layered services and legacy extraction systems that have been altered repeatedly over the years.
Nearby coverage connects Germiston with Wadeville, Alrode, Boksburg and Isando, but we do not copy one system design from area to area. Building geometry, production sequence, material characteristics and simultaneous machine use determine the final arrangement.

New machines should not simply be tee’d into an existing main without checking capacity and balance.
Established buildings often require careful coordination around beams, cranes and existing services.
We separate recoverable components from those that are genuinely undersized, damaged or unsuitable.

For Germiston projects involving legacy duct audits, maintainability is part of the design decision. Older duct runs can hide unused branches, leakage and abrupt changes that waste fan pressure. The final arrangement should allow the site team to inspect filters, flexible joints, access doors and fan condition without dismantling unrelated equipment. That matters because dust systems usually lose performance gradually, and visible access makes early faults easier to catch.
On a Germiston installation, machine additions has to be resolved together with the building layout. New machines should not simply be tee’d into an existing main without checking capacity and balance. We check clearances, support positions and how the system will be serviced after handover. The objective is not a visually impressive duct run that is difficult to maintain; it is a stable extraction path that fits the way the facility actually works.
A Germiston site where structural routing is the main concern needs the capture point checked while the process is operating, not only after shutdown. Established buildings often require careful coordination around beams, cranes and existing services. We then compare that requirement with the available route to the collector and the pressure the fan must overcome. For this type of job, small layout choices can determine whether suction remains useful at the machine furthest from the fan.
Consider repair versus replacement on a working Germiston production floor. We separate recoverable components from those that are genuinely undersized, damaged or unsuitable. The practical question is how that decision affects operators, cleaning, access and the next machine on the branch. Our assessment therefore follows the air path from the source through the hood and duct, rather than judging the system from the collector nameplate alone.
These examples are design situations, not assumptions about a particular premises. The final collector, filtration method, fan duty and safety controls must be selected from the actual material, process and site conditions.

A system that once worked can lose performance as filters load, ducting leaks, flexible connections collapse, machinery changes or extra branches are added. A system that never worked well may have a capture or layout problem rather than a simple motor fault.
We inspect the symptoms in the context of the full system before recommending repairs, duct changes, fan work or collector replacement.
The photos used across this dust-collection cluster are supplied project images from our commercial and industrial extraction work. They show the scale, routing and fabrication quality behind the systems we install and modify.
