Cleaner coolant for steadier deep-hole drilling
The coolant filtration unit is used to remove contamination from the coolant circuit before it returns to the machine. In gun-drilling and deep-hole boring, that matters because small particles can affect hole quality, tool life and pump condition. When coolant stays cleaner, flow stays more predictable and the machine is easier to keep on spec, especially on long production runs.
This is a practical addition for shops working on steel, stainless steel, cast materials and other demanding jobs where fine swarf builds up quickly. It is also useful where machines run for long shifts and the coolant is exposed to heat, chips and general contamination from the work area. In Benoni and across Gauteng, many customers ask for filtration support when they want less downtime and better repeatability.
Sizes and options for different machine setups
We supply filtration units in sizes and arrangements to suit different coolant volumes, machine layouts and production needs. The right unit depends on the machine type, coolant tank size, chip load and how the coolant is returned to the system. Some workshops need a compact unit that sits close to the machine, while others need a larger separate package for higher throughput.
- Compact units for single machines and smaller shops
- Standalone units for dedicated deep-hole boring lines
- Systems that can be matched to central coolant return loops
- Options for staged filtration, depending on the contamination level
- Layout choices for floor space, access and maintenance clearance
If you are running several machines in Johannesburg, Pretoria or Durban, it helps to plan the filtration arrangement around access for cleaning and safe movement around the machine. That keeps maintenance simple and avoids a cramped install later on.
Where the filtration unit suits best
This product suits manufacturers and engineering shops that need stable coolant quality during deep-hole work. It is a good fit for component repair work, production drilling, high-value parts and any operation where pump protection and coolant cleanliness matter. It also helps in shops where machine stoppages cost time and where coolant change-outs are expensive.
The unit is especially useful where swarf is fine and hard to remove by hand, or where the machine works with long duty cycles. Coastal humidity in places like Cape Town and Gqeberha can also make housekeeping and fluid condition more important, so a filtration system can form part of a broader maintenance routine. For inland sites, dusty environments and seasonal heat still place pressure on coolant quality.

- Production drilling cells
- Prototype and repair workshops
- Sites needing cleaner coolant for process stability
Installation, power supply and plant connections
Installation depends on the machine, the tank arrangement and the chosen pump package. Our team assists with placement, connection and commissioning so the unit works properly with the existing coolant circuit. We also look at access for cleaning, hose routing and safe service points before final handover. That is important in busy shops where machines cannot sit idle for long.
Electrical requirements depend on the final configuration and site conditions. We confirm the supply needed before installation so there are no surprises on the day. No gas supply is normally required for a coolant filtration unit. If your workshop has load-shedding or unstable supply, we can still help you plan for correct start-up, safe shutdown and practical operating routines around your power conditions.
- Check available electrical supply before ordering
- Allow space for maintenance access and filter changes
- Confirm coolant return points and tank layout
- Plan for safe drainage and containment at the install site
Care, servicing and routine checks
A filtration unit needs regular care to keep doing its job. That usually means checking the filter condition, cleaning or replacing consumables as needed, and keeping an eye on the coolant return path for signs of build-up. The aim is to stop contamination from moving back into the machine and to keep the coolant circuit stable through normal production work.
Our support team can assist with preventive maintenance, coolant system service, breakdown support and troubleshooting if the filtration performance changes. If the unit begins to block too quickly, loses flow or shows signs of carryover, it is worth checking the feed, the swarf load and the condition of the coolant itself. A quick inspection often saves a longer stop later on.
For shops in Benoni, the East Rand and wider Gauteng, regular service support is often the easiest way to keep the machine working without repeated interruptions. It is better to set a maintenance pattern than to wait for the coolant circuit to become a problem.
What to confirm before you place an order
Before ordering, it helps to confirm the machine type, the coolant tank size, the contamination level and the space available beside the machine. You should also know whether the unit is going onto one machine or feeding more than one. That information lets us recommend the most suitable arrangement and helps avoid wrong sizing.
- Machine model and current coolant circuit layout
- Expected chip type and contamination level
- Available floor space and access for service
- Electrical supply on site
- Whether you need a single-machine or shared solution
- Any timing needs for installation, commissioning or training
