4-4) Instructions to ensure the cooling air flow
To ensure the air flow from a fan rotor, please follow this instructions.
(1) Ensure the air intake
For PARAMAX DRIVE with a fan rotor, make more than 15mm gap between a fan hood and a screen
(ex. safety cover, fluid coupling). See Fig.8,Fig9
Narrow gap makes low air flow rate and the reducer can't be cooled enough.
If the air flow isn't disturbed, for example the safety cover is made by a expanded metal or so, the gap isn't needed.
From a view of Product liability law, avoid too much gap that make touchable hands to the rotational parts.
(2) Ensure the air flow way
For vertical mount and right angle shaft PARAMAX Drive with a fan rotor, make more than 10mm gap
under the reducer. See Fig.10
