a more consistent nozzle pressure and as a result be more effective. However, 

 with the use of a larger diameter hose from the compressor to the pressure pot, the 

 need for additional tank pressure could in all probability be eliminated. This 

 heavy-duty type of equipment need not run continuously in order to maintain 

 tank pressure and could efficiently deliver sufficient compressed air for the opera- 

 tion of a two-man program. As this item represents the largest single investment 

 for the work, it is economical in the long run to purchase a machine which 

 will withstand heavy-duty operation. 



Portable Equipment 



It is advisable to have the compressor, as well as the equipment, mounted on a 

 truck or be otherwise portable, in order to facilitate its movement around the 

 storage warehouses to be sealed. Where groups of warehouses are located at 

 relatively distant points, it is recommended that the compressor be mounted on
