With the exception of special usage for fuel oil EL, the nozzles can be used for all oils the viscosity of which does not exceed 5 cst (1.4\u00b0 E).
\nThe Type HO models (see below) can also be used for oils with a viscosity
\nup to 13 cst (2.1 \u00b0E).<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The series comprises 72 discharges from 1.5 l\/h to 378.5 l\/h (0.40 to 100 US GPH).
\nThe use of fuel oil EL at normal operating temperature may vary the discharge by approx. 1%.

The nozzles are tested at an operating pressure of 7 bar with fuel oil EL
\n(see discharge tables on the next page).
\nThe recommended operating pressure for nozzles (for fuel oil EL) is between 6 and 25 bar (please ask for using at higher pressure).
\nFor fluids with a higher viscosity, they can work with an operating pressure of 10 \u2013 14 bar. However, the spray angle decreases drastically (heavily), except if nozzles are used that are specially designed for such applications (see HO nozzle).<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

These filters, where all nozzles are equipped from 0.40 \u2013 1.00 GPH, achieve very good filtering (filter fineness 25 \u2013 50 microns).
\nThis filter has huge advantages to protect the nozzles with small discharges (under 1.00 GPH). The accumulation of small bronze balls forms a series of obstacles, which results in considerably better filtering than for simple screen filters. Therefore, the sensitive internal parts of the small nozzles are better protected. This filter withstands high temperatures.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Nozzles from 1.10 GPH to 9.5 GPH (4.16 \u2013 39.7 l\/h) discharge are all equipped with mesh strainers (Monel), mesh width 120. For larger discharges up to 30 GPH (113.5 l\/h), this type of filter can also be used, but is then separately supplied as an extra.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
