Latest Italian technology for industrial vacuum cleaning

Italian manufacturer Delfin is a global leader in industrial vacuum cleaners and suction units. The brand forms part of GCE’s product offering for standard industrial vacuuming, in addition to specialist solutions for hazardous environments, GCE National Sales Manager Peter Esterhuizen explains. “Our years of experience in industrial vacuum cleaning, combined with the backup and quality of the Delfin brand, places us in the position of being a leading solutions provider in this niche sector, offering the lowest total cost of ownership,” Esterhuizen comments. The Delfin Mistral 202 DS Dustop has two bypass motors, using carbon brushes and operated by independent switches, and placed inside a sturdy, noise-reducing plastic casing. The motor head has been designed to convey the exhaust air towards the ground, to avoid the user being affected by any dust. The filter is a high-surface conical cartridge (30 000 cm 2 ), with a one- micron filtration efficiency rate. The new Dustop filter-cleaning system allows the user to clean the filter efficiently and easily by simply pulling up the manual flap on the chamber five times while the vacuum is working. This simple operation maintains maximum filtration capacity and suction performance. The 50-mm-diameter suction inlet, with 50/38 mm The latest Italian technology for industrial vacuum cleaning is available from Goscor Cleaning Equipment, part of the Goscor Group.

In addition, the nylon filter prevents solid material from obstructing the floating device, or foam from penetrating the motor. 

The ARMSA tank standard The Association of Rotational Moulders of Southern Africa (ARMSA) announced the publication of a South African National Standard: SANS 1731:2017 for polyethylene chemical and water storage tanks, developed in conjunction with the South African Bureau of Standard (SABS).

• Ensures that the production methods used to manufacture the tanks comply with best practise • Requires that traceability is built into the manufacturer’s control systems. • Includes an audit check for actual storage volumes vs stated volumes • Evaluates the overall appearance of the finished tanks • Certifies the requisite number and type of fittings and the date of manufacture. Productivity Engineering and Services Consultants (PESC) an independent third party auditing company appointed by ARMSA will regularly audit tank manufacturers who choose to comply. If compliant, PESC will issue a certificate giving independent assurance of a manufacturer's claim that their products meet the SANS 1731:2017 criteria. Compliant tank manufacturers will be able

The SANS 1731:2017 tank standard is proof that the polyethylene tank you purchase has been properly designed and manufactured to be fit for purpose for the length of its warranty life. “It compels tank manufacturers to conform to world best practise,” explains Wayne Wiid, ARMSA Chairperson, “and it protects members of the broader construction, architecture, plumbing, landscaping and built industries as well as consumers, against tanks of lesser quality.” Sub header: What does the SANS 1731:2017 tank standard mean to the tank user • Provides specific criteria in terms of the source of raw material, ultra violet protection, overall weight, wall thickness, light penetration, stress crack resistance and impact strength for a range of different sizes.

A word of warning from Wiid, “Any tank manufacturer can claim to meet the SANS 1731:2017 standard but without formal certification there is no guarantee. We therefore urge all stakeholders and home owners to request the PESC certifi-cate from the manufacturer prior to purchase for peace of mind that tanks delivered to sites or homes have been thoroughly tested and certified.” 
