We are delighted to be working with Oakgrove Integrated College again, the College have taken delivery of a new Universal VLS4.75 60 watt laser paired with a BOFA AD Oracle iQ fume extraction system, creating a powerful and safe workspace for laser cutting and engraving across their curriculum.
The VLS4.75 is a free‑standing laser platform with a 24" x 18" (610 x 457 mm) work area and 8.5" (216 mm) Z‑height, giving students generous space for materials and fixtures. With a 60 watt CO₂ laser source, it comfortably cuts and engraves a wide range of materials typically used in schools, from 3 mm and 6 mm acrylic to plywood, card, textiles and laminates. The machine’s digital motion system and safety viewing window provide both precision and peace of mind for staff supervising busy classrooms.
To protect both users and equipment, Hobarts integrated the VLS4.75 with a BOFA AD Oracle iQ fume extraction unit, ducting and filters appropriate for the school’s material list. This complete setup ensures that fumes and particulates generated by laser processing are safely captured and filtered before being exhausted, keeping the teaching space clean and compliant.
The VLS4.75 laser cutter turns two‑dimensional designs into accurate physical prototypes by directing a focused laser beam over the 24" x 18" work area, allowing students to cut, engrave and mark materials with repeatable precision in a fully enclosed, interlocked system.
For students, one of the biggest benefits is the ability to move quickly from idea to prototype. A Year 9 design and technology class, for example, can sketch concepts, develop them in CAD and then send multiple variations to the laser in a single lesson. The 60 watt power level allows the machine to cut typical 3 mm acrylic at productive speeds, so pupils spend more time evaluating and iterating their designs and less time waiting for jobs to finish.
Safety is built into the VLS4.75 platform. The laminated safety glass viewing window lets staff visibly check progress without opening the door, while interlocks prevent the laser from operating if the door is not securely closed. In addition, over‑temperature monitoring in the work area provides an extra safeguard by triggering an alarm and shutdown if abnormal heat is detected. This combination of features gives teachers confidence to run back‑to‑back lessons with varying levels of student experience.
The machine’s digital motors provide smooth, precise motion without complex encoder systems, which contributes to both reliability and accuracy. In practice, this means that fine details in engraved graphics, small slots for press‑fit assemblies and delicate text are reproduced clearly.
The BOFA AD Oracle iQ fume extraction unit uses multi‑stage filtration and intelligent flow control to remove fumes and particulates from the laser process, protecting air quality, machine optics and sensitive components.
When cutting or engraving materials like acrylic, MDF or laminates, the laser produces a mix of fumes and fine particles. Without effective extraction, these can accumulate in the workspace, leading to unpleasant odours, potential health concerns and contamination of the laser optics. The AD Oracle iQ tackles this with a deep pleat pre‑filter and main combined filter, designed to capture both particulates and gases before clean air is returned or ducted away from the room.
Automatic Flow Control maintains consistent extraction performance as filters load, so staff do not have to constantly adjust settings. The iQ monitoring system provides real‑time data on filter status and airflow, enabling technicians to schedule filter changes proactively during quieter periods rather than reacting to unexpected downtime. In a busy school timetable, this level of predictability is invaluable.
Pairing a capable 60 watt laser with robust extraction also helps extend the life of the machine. Cleaner optics and a controlled internal environment reduce wear on components, meaning the school can expect more years of reliable service from its investment. Over the life of the system, the cost of high‑quality extraction is typically outweighed by the reduction in unplanned service calls and extended component life.
For staff and students, the most noticeable day‑to‑day benefit is a more pleasant classroom environment. Effective filtration significantly reduces lingering smells after laser use, allowing the room to be used immediately for the next lesson without disruption.
Hobarts supports the school not only with the supply of the VLS4.75 and BOFA AD Oracle iQ, but also with structured training, safety guidance and ongoing maintenance to keep the system performing at its best.
During handover, technicians and teaching staff receive practical training on everyday operation: starting up the system, loading materials correctly, selecting appropriate power, speed and PPI settings, and using recommended material profiles. Clear demonstrations help staff understand how to identify safe materials and avoid those that are unsuitable for laser processing.
Safety procedures are covered in detail, including pre‑use checks, supervision expectations and best practice for housekeeping around the laser area. For example, staff are shown how to confirm that extraction is operating correctly before each job, how to monitor for signs of poor airflow and what to do in the event of an alarm or abnormal behaviour.
To reduce downtime, Hobarts provides guidance on routine maintenance such as cleaning lenses and mirrors at appropriate intervals, checking and emptying the BOFA’s waste collection and monitoring filter status.
Beyond installation day, the school has access to technical support and service options tailored to education. This can include scheduled servicing, advice on new materials and help integrating laser work more deeply into schemes of work. The aim is to ensure that the investment continues to deliver value for many cohorts of students.
Hobarts is delighted to continue working with the school on this next chapter and looks forward to seeing how staff and students push the boundaries of what is possible with their new laser and extraction system !
