5 Application ngineering Information Q. What happens to the noise when I locate two blowers close together? A. If the blowers are of the same design they produce sound frequencies that are close together. These may cause a beating change in volume of the blower noise. This is because the units are not synchronized. If two small blowers are needed this change in volume can be reduced by moving tham further apart. With larger blowers a dual blower with two blowers on one motor will solve this problem. Q. What causes the noise relief valves make? A. Air rush through the valve. Q. ow do I control relief valve or bleed off valve noise? A. Attach A series silencer on the port of the relief valve that is open to atmosphere. ontact ast at --7 or with any further questions you may have on reducing blower noise in your application.

Note: or comparison purposes, some blower manufacturers show sound data from / meters instead of from meter; also, some blower manufacturers show an average sound level across performance instead of the full range between minimum and maximum sound levels; either of these methods will provide different and usually lower sound levels compared to ast s sound level method. da at Pressure da at Pressure R -7 R -4 R R - R 7-7 R -8 R4-7 R4 4- R4P -7 R4P 4-7 R 7-77 R 7-77 R 7-7 R 7-7 RP 8-8 RP 77-8 RPP 77-7 RPP 7-7 RPS 7-77 RPS 7-7 R R R7P 77-8 R7P 74-7 R7S 7-77 R7S 7-7 R 8-8 R 78-8 RP 8-88 RP 7-8 RS 7-8 RS 77-8 R4 8-8 R4 7-8 R4 8-8 R R7 8 R7 7-8 da at Vacuum da at Vacuum R 8- R 4- R 7 R -4 R 7-7 R 4- R4 7-7 R4-7 R4P 7-74 R4P 8-7 R 7-7 R 7-7 R 78-8 R RP 8-8 RP 7-8 RPP 8-8 RPP 78-7 RPS 7-8 RPS 7-77 R R R7P 84-8 R7P 8-8 R7S 8-8 R7S 78-8 R 8- R 8-84 RP 88- RP RS RS 8-8 R4 8-8 R R4 8-8 R4 8-8 R7 8- R7 8- ast anufacturing Inc., A Unit of IX orporation, enton arbor, I USA ph --7 fx Registered Trademark/ Trademark of ast anufacturing Inc., opyright ast anufacturing Inc.
