2 HUMDN CENTRFUGAL BLOWER EAGFC SERES] D DW (Double nlet Double Width) With Forwrd Curved mpeller When Qulity Speks For tself As leding mnufcturer of Centrifugl Blower Forwrd Curved ACFC Series, tody Humidin enjoys n envible position in customer mind-spce. Humidin bosts of modern plnt & tlented tem of qulified professionls who sets n excting stndrds of qulity for themselves. n sum, Humidin stnds for qulity & customer stisfction tht re instrumentl in bringing them on pr with wht the world clls the world clss.

3 Doub e nlet Forwrd Curved Centrifugl Blower The ACFC series Centrifugl Blower (Forwrd Curved) consist of Double nlet Double Width (DDW) centrifugl fns. These fns hve forwrd curved impellers with forwrd curved bldes hving specil profile to give you mximum efficiency t low noise levels. These impellers re stticlly nd dynmiclly blnced. The fns re suitble for vrious pplictions, where high volume ir displcement is required like Air Cooling, Generl Ventiltion, Pressuriztion etc., in commercil process nd industril HVAC systems Avilble Sizes : The ACFC Series is vilble in wheel size 5mm to 112mm dimeter. TYPE HUMDN ACFC series fns re designed for vrious duty ppliction nd re vilble in vrious type of construction, however, here in this ctlogue, we shll present only type-a TYPE - A The ACFC series is vilble in type A where strong side frme (M.S.) in welded construction re provided to support the Bering nd for wheel ssembly Fn size : 5 to 112 Volume : 1 to 1 m3/h Totl Pressure: 1 OOP to 16 P ACFC Twin Fn HUMDN lso mnufctures the twin fn mounted on single shft. For esiness in selection, plese, mke use of single fn curves, given in this ctlogue with following fctors: Volume x2 Absorbed Powerx 2.15 Speed xl.5 Noise x 3 db Type A2 Size : 5 to 63 Vol. :15 to 65 m3/h Note-Fn performnce for twin fn re not licensed byamca nterntionl

4 MPELLER H UMDN ACFC series impellers hve forwrd curved bldes mnufctured in G steel sheet. The bldes re die formed. The mpellers re stticlly nd dynmiclly blnced to SO 194 nd AMCA 24-G2.5 stndrds ø CASNG The csing for ll sizes is mnufcuted in G steel sheet nd re Pittsburg locked without ny surfce coting (optionl) SDE SUPPORTNG FRAME (MS) The side supporting frmes re fbricted out of MS section steel. The surfce is finished with enmel/epoxy cotings. GRN DED SHAFT The shft used for the fn re mde of EN-8/SAE-1 4 crbon steel nd mchined to the prescribed tolernces with stndrd keywys. The Shft re grinded for better performnce nd finish. The Shfts re coted with Vrnish/Lquer fter ssembly. BEARNGS HUMDN forwrd curved blower hve berings of interntionl stndrd. The Berings re either deep groove bll berings or sphericl roller berings with ccentric locking collrs/dptor sleeve seled t both sides. The Berings re pre lubricted nd re mintennce free. NLETCONE The Stndrd nlet Cones re mde of FRP, however for bigger sizes the fbricted nlet Cones, mde of sheet steel mteril re provided. The nlet Cones re designed Aerodynmiclly for better efficiency. Drin Plug in csing - optionl. Outlet Flnges - optionl. nspection Doors - optionl (one position). Gurds t nlet or outlet re optionl www humidin corn 2

5 - Fn Rottion nd Dischrge The rottion nd dischrge of the fn is in ccordnce with AMCA stndrd The direction of rottion is determined from the drive end of the fn CW CCW - clockwise rottion counter-clockwise rottion Fn rottion nd dischrge Motor Selection Motor Position The power curve shown on ech performnce curve represents the bsorbed power t the shft of the fn mesured in kw. The position of the motor for belt drive centrifugl fn is stndrd in ccordnce with AMCA To determine the power of the motor to be instlled, correction fctor should be pplied to compenste for trnsmission losses. Loction of motor is determined by fcing the drive side of fn nd designting the positions by letters W, X, Y & Z. For conversion to horsepower (HP), use multiplying fctor S S.1 Y 1Fx Motor Position Motor power output (KW) Recommended for compenstion

6 DYNAMC PRESSURE PERFORMANCE The dynmic pressure nd outlet ir velocity shown on ech curved re clculted on the full ir dischrge re, i.e. ducted outlet conditions. The performnce dt shown on ech digrm hs been tested nd mesured Stndrd 21. in ccordnce to AMCA With free outlet conditions, the velocity pressure higher. To determine this new vlue, multiply the velocity pressure of the ducted outlet obtined from the fn curve by the following correction fctor 11 is K. Fn performnces clcult with this correction fctors re not licensed by AMCA nterntionl. [K=26] Rtings re referred to the stndrd ir density with the totl pressure s logrithmic scles. t is function of the ir volume, using essentil tht, the sme instlltion type nd test stndrd re used t ll times, when compring fn NOSE The nose level shown on ech digrm refer to the sound power A-weighted nd the dt on the inlet side hs been mesured determined s follows: in ccordnce with AMCA Stndrd 3 configurtion B.
