Evergreen trees do give off oxygen. They give off less oxygen than deciduous trees do in the summer, but they do release oxygen all year.
Define a "normal" tree; banyans are by no means extraordinary or any more special than any other type. Trees (in general and for the most part) produce huge amounts of oxygen, because of their size and the number of them that exist. However, in terms of the amount of oxygen-producing capability per amount of tree (in mass) they are fairly inefficient, and broadleafed plants are better for oxygen production by natural means.
Peepus tree
A tree absorbs carbon dioxide from the air, and, with the input of energy from sunlight, oxidizes many of the oxygen atoms of the absorbed carbon dioxide to elemental oxygen, which is released into the atmosphere. The carbon and some of the oxygen atoms from the absorbed carbon dioxide are incorporated into the structure of the tree as the tree grows.

The mango tree releases oxygen during day time.
does tulsi &peepal tree produce oxygen
Transpiration occurs when plants and tree's release water and oxygen as a byproduct of photosynthesis.

You get oxygen and beauty from tree's and other plants.
A koala on a eucalyptus tree does not affect the oxygen.
A tree takes in carbon dioxide, and returns oxygen to the atmosphere.

Simply cutting a tree wouldn't consume oxygen, other than what you'd use while breathing or the oxygen your chainsaw consumes. You would lose the potential to create oxygen that the tree would otherwise do.
A dog breathes in oxygen and then releases carbon dioxide when he exhales. Conversely, a tree gives off oxygen and takes in carbon dioxide. So the breath of the dog sustains the tree, while the output of oxygen from the tree sustains the dog.
Peepus tree
Ficus religiosa (Peepal Tree) gives oxygen at night also.
