Side cooling
Air-cooled v30 (SAG) lasers are shipped without cooling fans so customers must provide some type of air
cooling to prevent overheating. SYNRAD recommends using two cooling fans rated for at least 4.0 m
3
/
min (140 CFM) at a static air pressure of 13.2 mm H
2
O (0.52 in H
2
O). The cooling fans should measure
approximately 120 × 120 mm (4.7" × 4.7") and have at least 57.2 mm (2.25") of unobstructed clearance
between the outside edge of the fan housing and any mounting surface or enclosure.
The OEM v30 does not provide a voltage output sufficient to power cooling fans, so customers must pro-
vide an external power source to drive the selected cooling fans. Because of the heat generated by internal
RF circuitry, establishing significant airflow evenly over the entire surface of the combined laser/RF chassis
is vitally important to the performance and longevity of the laser.
For free-space mounting (no fan shroud), position the fans symmetrically as shown in Figure 1-4 where
they are centered horizontally with the laser chassis and vertically with the heatsink fins. Position both
fans so the inside face is no more than 76 mm (3.0") from the v30’s heatsink fins.

Recommended v30 cooling fan locations – free-space cooling
When using a tight-fitting fan shroud designed for side cooling, the cooling fans can be positioned within
5–25 mm (0.20–1.0") of the heatsink fins as long as the same gap is maintained on either side.
Rear cooling
A fan shroud designed for rear cooling can be used to minimize the length of the laser installation as
shown in Figure 1-5. The shroud should enclose the full length of the laser and cooling fan and must fit
snugly against the laser’s heatsink fins. Use a fan rated for at least 8.5 m
3
/min (300 CFM) at a static air
pressure of 23.9 mm H
2
O (0.94 in H
2
O) and position it approximately 150 mm (6.0") from the rear of the
laser.
