Dust & Fumes

WHEN LYN DEN OVER, A HIGHLY RE­GARDED AND AWARD-WIN­NING NEW ZEALAND GLASS ARTIST NEEDED BET­TER EX­TRAC­TION IN HIS TAUPO BASED WORK­SHOP, HE CON­TACTED NZ DUCT+ FLEX IN AUCK­LAND TO SOLVE THE EX­TRAC­TION IS­SUES AT THE VAR­I­OUS STAGES OF HIS MAN­U­FAC­TUR­ING PROCESS.

Trained at North Tec in Whangarei, Lynden holds a bach­e­lor’s de­gree in ap­plied arts. On the com­ple­tion of his study he con­tin­ued to work in glass and ini­tially rented a lo­cal glass stu­dio where he de­vel­oped his own orig­i­nal range of col­lectable art glass­ware.

In 2002 Lynden moved to Taupo and opened Lava Glass stu­dio and gallery. Here Lynden has had the free­dom to ex­tend his pro­duc­tion range. He started to work on his range of large glass works, cre­at­ing some award- win­ning art glass pieces. How­ever as the man­u­fac­tur­ing in­creased, so did the ef­fect on the work­shop en­vi­ron­ment: it got dusty. Now a key tourist at­trac­tion, it was im­por­tant for Lynden that his work­shop was not just about the art, but about the safety is­sues as well.

Dur­ing the ‘blow­ing’ phase when the glass is be­ing formed, as it cools, fine par­ti­cles not vis­i­ble to the naked eye are cre­ated. Af­ter dis­cus­sion with NZDUCT+FLEX it was agreed that these par­ti­cles could be cap­tured with Fume Arms, whilst other effluent cre­ated over the ‘rolling’ bench are now cap­tured by be­spoke down­draft hoods sur­round­ing the form­ing and shap­ing bench.

NZDUCT+FLEX sup­ply a range of fume arms from Eu­ro­pean sup­pli­ers that vary from small lab arms to the most pop­u­lar in­dus­trial sized 3m or 4m reach arms. “These blue/yel­low arms that you see ev­ery­where have ex­ter­nal hing­ing and are eas­ily the best value for money cur­rently in the NZ mar­ket,” com­ments Ge­off Eb­don , Sales Man­ager. The out­side hinge en­sures the arm doesn’t jam or get stiffer with con­stant ma­te­rial abrad­ing the hinges, and with the ‘all round’ han­dle to po­si­tion the arm eas­ily, the re­sult is that when be­ing used by an in­di­vid­ual welder, it is po­si­tioned cor­rectly and can be ad­justed with one hand to max­imise the Health and Safety ben­e­fit to the worker.

Ev­ery­thing, in­clud­ing dust from the glass grind­ing and pol­ish­ing sec­tion, is then fil­tered through the two-bay bag emp­ty­ing mod­u­lar fil­ter from an­other Eu­ro­pean sup­plier JKF In­dus­tri who also make the fans. In this in­stance a JK 30D ma­te­rial han­dling fan with a 5.5kW mo­tor was cho­sen. To link the whole sys­tem, all the com­po­nents in­cluded the LI­PLOCK mod­u­lar duct­ing sys­tem also from the Dan­ish sup­plier, hence com­pat­i­bil­ity and per­for­mance of the whole in­stal­la­tion is as­sured.

Whilst mod­u­lar bag­houses are one of the older fil­ter meth­ods, they are very cost ef­fec­tive for high air vol­umes and heavy dust loads.

Hav­ing an in- house in­stal­la­tion team re­sults in big time sav­ings for NZDUCT+FLEX and their cus­tomers, and an ex­cel­lently fin­ished job, as the team are in­stalling these prod­ucts con­stantly all over the NZ week af­ter week. Lynden was pleased with how quickly the unit went up and the im­me­di­ate im­prove­ment in his work space.
